Pertama kita mulai mengkonfigurasi IP addressnya

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config)#int se0/0
R1(config-if)#no sh
R1(config-if)#ip add 12.12.12.1 255.255.255.0

R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int s0/0
R2(config-if)#no sh
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#int f0/0
R2(config-if)#no sh
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#ex

R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#int fa0/0
R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

Kemudian kita konfigurasi routing eigrp

R1(config)#router eigrp 10
R1(config-router)#no au
R1(config-router)#net 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.0 0.0.0.0
R1(config-router)#ex

R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 12.12.12.0 0.0.0.0 
R2(config-router)#net 2.2.2.2 0.0.0.0
R2(config-router)#net 23.23.23.0 0.0.0.255

R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#net 23.23.23.0 0.0.0.0
R3(config-router)#ex

Selanjutnya kita konfigurasi interace loopback tambahan di router 3

R3(config)#int lo1
R3(config-if)#ip add 10.10.10.1 255.255.255.255

R3(config-if)#int lo2                         
R3(config-if)#ip add 10.10.10.5 255.255.255.252
R3(config-if)#int lo3                         
R3(config-if)#ip add 10.10.10.9 255.255.255.248   
R3(config-if)#int lo4
R3(config-if)#ip add 10.10.10.25 255.255.255.240  
R3(config-if)#ex

konfigurasi sumari di eigp 10 di router 3

R3(config)#router eigrp 10
R3(config-router)#net 0.0.0.0
R3(config-router)#ex

selanjutnya cek tabel routingnya di router 2

R2(config)#do sh ip ro
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

     1.0.0.0/32 is subnetted, 1 subnets
D       1.1.1.1 [90/409600] via 12.12.12.1, 00:31:10, FastEthernet0/0

     12.0.0.0/24 is subnetted, 1 subnets
C       12.12.12.0 is directly connected, FastEthernet0/0
R2(config)#

SElanjutnya lakukan konfigurasi Filtering - Prefix List - Out di router 3

R3(config)#ip prefix-list EIGRP_OUT seq 5 deny 10.10.10.0/24 ge 27 le 30
R3(config)#ip prefix-list EIGRP_OUT seq 10 permit 0.0.0.0/0 le 32
R3(config)#router eigrp 10
R3(config-router)#distribute-list prefix EIGRP_OUT out
R3(config-router)#ex

Selanjutnya cek tabel routing di router 2
R2(config)#do sh ip ro

R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

Kemudian kita konfigurasi routing eigrp

R1(config)#router eigrp 10
R1(config-router)#no au
R1(config-router)#net 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.0 0.0.0.0

Selanjutnya kita konfigurasi interace loopback tambahan di router 3

R3(config)#int lo1
R3(config-if)#ip add 10.10.10.1 255.255.255.255

kemudian tambahkan defaut route pada router 3

R3(config)#ip route 0.0.0.0 0.0.0.0 Null 0

senjutnya konfigurasi redistribute static di router 3 routing eigrpnya

R3(config)#router eigrp 10
R3(config-router)#redistribute static

Selanjutnya kita cek di route R1 tabel routingnya

Selanjutnya kita coba lakukan ping

D*EX 0.0.0.0/0 [170/2195456] via 12.12.12.2, 00:00:13, Serial0/0
R1#ping 10.10.10.1

Alhamdulillah kita masih bisa bertemu sharing sharing tentunya di sinaubareng19 kali ini kita akan melanjutkan yang sebelumnya yaitu yang redistribute static, kali ini kita akan membahas tentang redistribute RIP, untuk topologi kita masih sama seprti yang sebelumnya yaitu seperti dibawah ini.

Pertama kita mulai mengkonfigurasi IP addressnya

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config)#int se0/0

Kemudian kita konfigurasi routing eigrp

R1(config)#router eigrp 10
R1(config-router)#no au
R1(config-router)#net 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.0 0.0.0.0

Selanjutnya kita konfigurasi interace loopback tambahan di router 3

R3(config)#int lo1
R3(config-if)#ip add 10.10.10.1 255.255.255.255

Selanjutnya kita konfiugrasi Routing RIP di router 3, epatnya di network lo1

R3(config)#router rip
R3(config-router)#ve 2
R3(config-router)#net 10.10.10.1          
R3(config-router)#no au       
R3(config-router)#redistribute eigrp 10 metric 10

Selanjutnya di Eigrpnya kita redistribute RIP.

R3(config)#router eigrp 10
R3(config-router)#redistribute rip metric 1 1 1 1 1
R3(config-router)#ex

Selanjutnya pada router 1 kitacek tabel route dan lakukan ping

R1(config)#do sh ip ro

Alhamdulillah kita masih diberikan kesempatan untuk Sharing bersama lagi, melanjtkan materi yang kemarin yaitu tentang Konfigurasi EIGRP - Default Route - Summary Address sekarang kita akan menkonfigurasi EIGRP - Redistribution Connected. sepertibiasa kita mulai dari membuat topologi terlebih dahulu. buatlah seperti dibawwah ini.

Kemudian kita mulai mengkonfigurasi IP addressnya

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config)#int se0/0
R1(config-if)#no sh
R1(config-if)#ip add 12.12.12.1 255.255.255.0

R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int s0/0
R2(config-if)#no sh
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#int f0/0
R2(config-if)#no sh
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#ex

R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#int fa0/0
R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

Kemudian kita konfigurasi routing eigrp

R1(config)#router eigrp 10
R1(config-router)#no au
R1(config-router)#net 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.0 0.0.0.0
R1(config-router)#ex

R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 12.12.12.0 0.0.0.0 
R2(config-router)#net 2.2.2.2 0.0.0.0
R2(config-router)#net 23.23.23.0 0.0.0.255

R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#net 23.23.23.0 0.0.0.0
R3(config-router)#ex

Selanjutnya kita konfigurasi interace loopback tambahan di router 3

R3(config)#int lo1
R3(config-if)#ip add 10.10.10.1 255.255.255.255
R3(config-if)#int lo2                         
R3(config-if)#ip add 10.10.10.2 255.255.255.255
R3(config-if)#int lo3                         
R3(config-if)#ip add 10.10.10.3 255.255.255.255

Kemudian lakukan konfigurasi Redistribute connected

R3(config)#router eigrp 10
R3(config-router)#redistribute connected

kemdian kita cek tabel route nya di router 1

kemudian kita coba ping

R1(config)#do ping 10.10.10.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.10.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/10/20 ms
R1(config)#

Assalamualaikum wr wb

Alhamdulillah kita masih diberikan kesempatan untuk Sharing bersama lagi, melanjtkan materi yang kemarin yaitu tentangKonfigurasi EIGRP - Equal Load Balancing  tapi sekaran gkita akan membahas yaiu Konfigurasi EIGRP - Default Route - Summary Address. buatlah topologi seperti dibawah ini.

Pertama kita tambahkan IP address di masing masing interface router.

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config)#int se0/0
R1(config-if)#no sh
R1(config-if)#ip add 12.12.12.1 255.255.255.0

R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int s0/0
R2(config-if)#no sh
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#int f0/0
R2(config-if)#no sh
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#ex

R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#int fa0/0
R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

Kemudian kita konfigurasi routing eigrp

R1(config)#router eigrp 10
R1(config-router)#no au
R1(config-router)#net 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.0 0.0.0.0
R1(config-router)#ex

R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 12.12.12.0 0.0.0.0 
R2(config-router)#net 2.2.2.2 0.0.0.0
R2(config-router)#net 23.23.23.0 0.0.0.255

R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#net 23.23.23.0 0.0.0.0
R3(config-router)#ex

Selanjutnya kita konfigurasi interace loopback tambahan di router 3

R3(config)#int lo1
R3(config-if)#ip add 10.10.10.1 255.255.255.255
R3(config-if)#int lo2                         
R3(config-if)#ip add 10.10.10.2 255.255.255.255
R3(config-if)#int lo3                         
R3(config-if)#ip add 10.10.10.3 255.255.255.255

Selanjutnya masih di router 3 tepatnya di interface f0/0, kita konfigurasi sumary address eigrp.

R3(config)#int fa0/0
R3(config-if)#ip summary-address eigrp 10 0.0.0.0 0.0.0.0  
R3(config-if)#ex

Selanjutnya kita cek tabel routing di router 1

R1(config)#do sh ip ro
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is 12.12.12.2 to network 0.0.0.0

     1.0.0.0/32 is subnetted, 1 subnets
C       1.1.1.1 is directly connected, Loopback0
     2.0.0.0/32 is subnetted, 1 subnets
D       2.2.2.2 [90/2297856] via 12.12.12.2, 00:02:46, Serial0/0
     23.0.0.0/24 is subnetted, 1 subnets
D       23.23.23.0 [90/2195456] via 12.12.12.2, 00:00:57, Serial0/0
     12.0.0.0/24 is subnetted, 1 subnets
C       12.12.12.0 is directly connected, Serial0/0
D*   0.0.0.0/0 [90/2323456] via 12.12.12.2, 00:00:20, Serial0/0
R1(config)#

Selanjutnya kita coba ping kesatu sama lain.

R1(config)#do ping 10.10.10.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.10.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/17/44 ms
R1(config)#

pertama kita buat topologi seperti dibawah ini

Konfigurasi IP addressnya terlebih dahulu
R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int e0/0
R1(config-if)#no sh

R4(config-if)#no sh
R4(config-if)#ip add 34.34.34.4 255.255.255.0
R4(config-if)#ex

Selanjutnya konfiguasi routing eigrp
R1(config)#router eigrp 10
R1(config-router)#no au
R1(config-router)#net 0.0.0.0
R2(config)#router eigrp 10
R2(config-router)#no au

R3(config-router)#no au
R3(config-router)#ex
R4(config)#router eigrp 10
R4(config-router)#net 0.0.0.0
R4(config-router)#no au

Kemudian cek tabel routingnya

Alhamdulillah kita masih bisa sharing kembali tentunyadi belajar IT Bersama, kali ini kita akn membahas mengenai cara konfigurasi EIGRP - Mindah Jalur - AD, pertama buat topologi seperti dibawah ini

 Jika kita memperhatikan topologidiatas maka normal tentuya trafik dari router R1 menuju loopback R3 adalah langsung menuju router R3 melalui interface f1/0 karena perhitungan bandwidthnya. Bila diinginkan trafik melewati router R2 dulu maka parameter metric bisa kita rubah agar memenuhi hal tersebut, salah satunya adalah AD. Langsung ke konfigurasi pertama kita konfigurasi IP  addressnya terlebih dahulu

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int s2/0
R1(config-if)#no sh
R1(config-if)#ip add 12.12.12.1 255.255.255.0
R1(config-if)#int e0/0
R1(config-if)#no sh
R1(config-if)#ip add 13.13.13.1 255.255.255.0

R2(config)#int l0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int s2/0
R2(config-if)#no sh
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#int e0/0
R2(config-if)#no sh
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#ex

R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#int e0/0
R3(config-if)#no sh
R3(config-if)#ip add 13.13.13.3 255.255.255.0
R3(config-if)#int e0/1
R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

Kemudian kita konfigurasi roter eigrp di router 1,2,3

R1(config)#router eigrp 10
R1(config-router)#no au
R1(config-router)#net 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.0 0.0.0.255

R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 2.2.2.2 0.0.0.0
R2(config-router)# net 23.23.23.0 0.0.0.255 
R2(config-router)#net 12.12.12.0 0.0.0.255

R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 23.23.23.0 0.0.0.255
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#net 13.13.13.0 0.0.0.255
R3(config-router)#ex

Kemudian kita cek route nya

Saatnya kita blokrisatau melarang lewat langsung ke router , harus lewat router 2

R1(config)#access-list 10 permit 3.3.3.3
R1(config)#router eigrp 10
R1(config-router)#distance 255 13.13.13.0 0.0.0.255 10
R1(config-router)#ex

Kemudian kica cek lagi tabel routingnya

Kemudian kita cek tabel routingnya

Sekarang manipulasi trafiknya, offset nya diset dengan nilai yang paling besar yakni 2147483647

R1(config)#access-list 10 permit 3.3.3.3
R1(config)#router  eigrp 10
R1(config-router)#offset-list 10 in 2147483647 e0/0

R3(config-router)#net 13.13.13.0 0.0.0.255
R3(config-router)#ex

Jika router 1 ingin berkomunikasi dengan 3.3.3.3 secara logika akan menggunakan jalur e0/0 seperti ganbar dibawah ini

Kalo kemarin kita memindahkan jalur dengan merubah delay sekaran merubah jalur menggunakan banwith, coba lihat perbedaan banwithnya

Selanjutnya kita memanipulasi banwithnya

R1(config-if)#int e0/0
R1(config-if)#bandwidth 1000
R1(config-if)#do clear ip eigrp ne

Selanjutnya kita buka lagi apakah sudah ada perubahan belum

Selanjutnya kita cek lagi lewat mananya

R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

Kemudian kita konfigurasi roter eigrp di router 1,2,3

R1(config)#router eigrp 10
R1(config-router)#no au
R1(config-router)#net 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.0 0.0.0.255
R1(config-router)#net 13.13.13.0 0.0.0.255
R1(config-router)#ex

R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 2.2.2.2 0.0.0.0
R2(config-router)# net 23.23.23.0 0.0.0.255 
R2(config-router)#net 12.12.12.0 0.0.0.255

R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 23.23.23.0 0.0.0.255
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#net 13.13.13.0 0.0.0.255
R3(config-router)#ex

Kemudian kita cek jika router 1 ingin ke router 3 tepatya ke ip loopback itu lewat mana

Bisa dilihat bahwah lewatnya network 13.13.13.0/24, selanjutnya Selanjutnya lakukan pengecekan pada EIGRP Topologi nya untuk memastikan ada beberapa jalur menuju ke 3.3.3.3

Terlihat banwidh e0/0 adalah 10000 kb sedangkan serial lebih kecil yaitu 1544 kb dan delaynya pun berbeda e0/0 6000 sedangkan serial 26000 maka tak heran router 1 lebih memilih langsung ke router 3 daripada harus lewat router 2 terlebih dahulu.

Untuk merubah jalurnya, kita memanipulasi nilai metricnya dengan merubah delay

R1(config)#int e0/0
R1(config-if)#delay 30000
R1(config-if)#do clear ip eigrp ne

kemudian kita cek lagi

R1(config-if)#do sh ip eigrp topology 3.3.3.3 255.255.255.255

Terlihat ada perubahan delai di e0/0 menjadi 305000sehingga jalurnya berubah, untuk memastikannya kita cek saja

Assalamualaikum wr wb

Assalamualaikum wr wb Alhamdulillah kita masih bisa sharing kembali tentunyadi belajar IT Bersama, kali ini kita akn membahas mengenai cara konfigurasiEigrp - Unicast Update. EIGRP secara default, updatenya secara multicast ( 224.0.0.10 ). Diinginkan agar updatenya tidak lagi secara multicast melainkan secara unicast, langsung lanjut ke konfigurasinya pertama kita buat topologi yang sederhana dulu seperti dibawah ini

kemudian kita konfigurasi IP addressnya

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int se2/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0 
R1(config-if)#no sh
R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int s2/0
R2(config-if)#no sh
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#int e0/0                         
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#no sh
R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.0  
R3(config-if)#int e0/0
R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

kemudian kita konfigurasi roter eigrp di router 1,2,3

R1(config)#router eigrp 10
R1(config-router)#no au 
R1(config-router)#net 1.1.1.1 0.0.0.0 
R1(config-router)#net 12.12.12.0 0.0.0.255
R1(config-router)#ex
R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 2.2.2.2 0.0.0.0 
R2(config-router)#net 12.12.12.0 0.0.0.255
R2(config-router)#net 23.23.23.0 0.0.0.255
R2(config-router)#ex
R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#net 23.23.23.0 0.0.0.255

Secara default EIGRP melakukan update secara multicast (224.0.0.10)

R1(config-router)#do  debug ip  packet detail

kemudian kita konfigurasi untuk merubahnya menjadi unicast, konfigurasi seperti dibawah ini

R1(config)#router eigrp 10
R1(config-router)#neighbor 12.12.12.2 s2/0

Dan di router 2 juga

R2(config)#router eigrp 10
R2(config-router)#neighbor 12.12.12.1 s2/0

kemudian kita cek lagi

R1(config-router)#do  debug ip  packet detail

Assalamualaikum wr wb

Alhamdulillah kita masih bisa sharing kembali tentunyadi belajar IT Bersama, kali ini kita akn membahas mengenai cara konfigurasi Eigrp Summarization, untuk topologinya kita masih sama seprti yang sebelumnya.

Summarization ini berfungsi untuk meringkas tael routing. langsung konfigurasinya pertama kita kofiguurasi IP addressnya

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int se2/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0 
R1(config-if)#no sh
R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int s2/0
R2(config-if)#no sh
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#int e0/0                         
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#no sh
R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.0  
R3(config-if)#int e0/0
R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

kemudian kita konfigurasi roter eigrp di router 1,2,3

R1(config)#router eigrp 10
R1(config-router)#no au 
R1(config-router)#net 1.1.1.1 0.0.0.0 
R1(config-router)#net 12.12.12.0 0.0.0.255
R1(config-router)#ex
R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 2.2.2.2 0.0.0.0 
R2(config-router)#net 12.12.12.0 0.0.0.255
R2(config-router)#net 23.23.23.0 0.0.0.255
R2(config-router)#ex
R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#net 23.23.23.0 0.0.0.255

Selanjutnya kita menambahkan interface loopback di ruter 3

R3(config)#int lo1
R3(config-if)#ip add 10.10.10.1 255.255.255.255
R3(config-if)#int lo2                         
R3(config-if)#ip add 10.10.10.2 255.255.255.255

R3(config-if)#int lo3
R3(config-if)#ip add 10.10.10.3 255.255.255.255
R3(config-if)#int lo4
R3(config-if)#ip add 10.10.10.4 255.255.255.255
R3(config-if)#int lo5                         
R3(config-if)#ip add 10.10.10.5 255.255.255.255
R3(config-if)#int lo6                         
R3(config-if)#ip add 10.10.10.6 255.255.255.255
R3(config-if)#int lo7                         
R3(config-if)#ip add 10.10.10.7 255.255.255.255
R3(config-if)#

kemudian kita konfigurasi routing eigrp pada network loopback

R3(config)#router eigrp 10
R3(config-router)#net 10.10.10.1 0.0.0.0
R3(config-router)#net 10.10.10.2 0.0.0.0
R3(config-router)#net 10.10.10.3 0.0.0.0
R3(config-router)#net 10.10.10.4 0.0.0.0
R3(config-router)#net 10.10.10.5 0.0.0.0
R3(config-router)#net 10.10.10.6 0.0.0.0
R3(config-router)#net 10.10.10.7 0.0.0.0
R3(config-router)#no au

selanjutnya di router 1 kita cek tabel routing

R1(config)#do sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

R1(config)#

banyakkan jumlah routing pada tabel routing, untuk merinkasnya kita lakukan sumary seperti berikut di router 3

R3(config)#int e0/0                                      
R3(config-if)# ip summary-address eigrp 10 10.0.0.0 0.0.0.0 
R3(config-if)#

Selanjutnya kita cek tabel routing lagi

R1(config)#do sh ip route

Assalamualaikum wr wb

Alhamdulillah kita masih bisa berjumpa untuk sharing kembali, tentunya di Belajar IT bersama, kali ini kita akan melanjutkan lab yang kemaring yaitu tentang routing eigrp, kali ini kita akan membahas tentang Eigrp Authentication. pertama buat topologi seperti dibawah ini.

kemudian kita mulai konfigurasi IP address dan routing eigrp

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int se2/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0 
R1(config-if)#no sh
R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int s2/0
R2(config-if)#no sh
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#int e0/0                         
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#no sh
R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.0  
R3(config-if)#int e0/0
R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

kemudian kita konfigurasi roter eigrp di router 1,2,3

R1(config)#router eigrp 10
R1(config-router)#no au 
R1(config-router)#net 1.1.1.1 0.0.0.0 
R1(config-router)#net 12.12.12.0 0.0.0.255
R1(config-router)#ex
R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 2.2.2.2 0.0.0.0 
R2(config-router)#net 12.12.12.0 0.0.0.255
R2(config-router)#net 23.23.23.0 0.0.0.255
R2(config-router)#ex
R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#net 23.23.23.0 0.0.0.255

kemudian kita mulai mengkonfiugrasi Eigrp Authentication ,pertama di router 1 terlebih dahulu

R1(config)#key chain eigrp
R1(config-keychain)#key 2
R1(config-keychain-key)#key-string CISCO
R1(config-keychain-key)#int s2/0
R1(config-if)#ip authentication key-chain eigrp 10 eigrp
R1(config-if)#ip authentication mode eigrp 10 md5
R1(config-if)#ex

kemudain konfigurasi yang sama di router 2

R2(config)#key chain eigrp
R2(config-keychain)#key 2
R2(config-keychain-key)#key-string CISCO
R2(config-keychain-key)#int s2/0
R2(config-if)#ip authentication mode eigrp 10 md5
R2(config-if)#ip authentication mode eigrp 10 md5
R2(config-if)#ip authentication key-chain eigrp 10 eigrp

selanjutnya cek dengan debug

R1(config)#do debug eigrp packets

Assalamualaikum wr wb

Alhamdulillah kita masih bisa sharing kembali tentunyadi belajar IT Bersama, kali ini kita akn membahas mengenai cara konfigurasi Eigrp redistribute OSPF, unutk topologinya kita masih sama seprti yang sebelumnya.

Pertama kita konfigurasi IP addressnya di semua router

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int se2/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0 
R1(config-if)#no sh
R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int s2/0
R2(config-if)#no sh
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#int e0/0                         
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#no sh
R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.0  
R3(config-if)#int e0/0
R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

kemudian kita konfigurasi roter eigrp di router 1,2,3

R1(config)#router eigrp 10
R1(config-router)#no au 
R1(config-router)#net 1.1.1.1 0.0.0.0 
R1(config-router)#net 12.12.12.0 0.0.0.255
R1(config-router)#ex
R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 2.2.2.2 0.0.0.0 
R2(config-router)#net 12.12.12.0 0.0.0.255
R2(config-router)#net 23.23.23.0 0.0.0.255
R2(config-router)#ex
R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#net 23.23.23.0 0.0.0.255

selanjutnya kita menambahkan interface loopback di ruter 3

R3(config)#int lo1
R3(config-if)#ip add 10.10.10.1 255.255.255.255
R3(config-if)#int lo2                         
R3(config-if)#ip add 10.10.10.2 255.255.255.255

selanjutnya kita konfiugrasi routing Ospf di router 1 da lakukan redistribute juga

R3(config)#router ospf 10
R3(config-router)#no au
R3(config-router)#net 10.10.10.1 0.0.0.0 ar 0
R3(config-router)#net 10.10.10.2 0.0.0.0 ar 0
R3(config-router)#redistribute eigrp 10 metric 10

selanjutnya dari routing eigrp kita konfigurasi redistribute OSPF

R3(config)#router eigrp 10
R3(config-router)#redistribute ospf 10 metric 1 1 1 1 1
R3(config-router)#ex

selanjutnya kita cek di tabel routing

R1(config-if)#do sh ip ro                   
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
       a - application route
       + - replicated route, % - next hop override

Gateway of last resort is not set

Alhamdulillah kita masih bisa bertemu kembali tentunya di Belajar IT Bersama,
setelah kemarin kita membahas tentang bagaimana Filter Network yang
masuk dengan EIGRP sekarang kita akan membahas tentang Filtering IP ganjil
genap di EIGRP. Pertama kita buat topologinya seprti berikut ini.

Pertama kita konfigurai IP addressnya terlebih dahulu,

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int e0/0
R1(config-if)#no sh
R1(config-if)#ip add 12.12.12.1 255.255.255.0
R1(config-if)#ex

R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int e0/0
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#no sh
R2(config-if)#int e0/1
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#no sh
R2(config-if)#ex

R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#int e0/0
R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

kemudian kita konfigurasi routing eigrpnya

R1(config)#router eigrp 10
R1(config-router)#no au
R1(config-router)#net 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.0 0.0.0.255
R1(config-router)#ex
R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 2.2.2.2 0.0.0.0
R2(config-router)#net 12.12.12.0 0.0.0.255
R2(config-router)#net 23.23.23.0 0.0.0.255
R2(config-router)#ex
R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 23.23.23.0 0.0.0.255
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#ex

Kemudian kita konfigurasi ip loopback di router 3 sampai 1 loopback

R3(config)#int lo1
R3(config-if)#ip add 10.10.10.1 255.255.255.255
R3(config-if)#int lo2
R3(config-if)#ip add 10.10.10.2 255.255.255.255
R3(config-if)#int lo3
R3(config-if)#ip add 10.10.10.3 255.255.255.255
R3(config-if)#int lo4
R3(config-if)#ip add 10.10.10.4 255.255.255.255
R3(config-if)#int lo5
R3(config-if)#ip add 10.10.10.5 255.255.255.255
R3(config)#int lo6
R3(config-if)#ip add 10.10.10.6 255.255.255.255
R3(config-if)#int lo7
R3(config-if)#ip add 10.10.10.7 255.255.255.255
R3(config-if)#ex

Selanjutna kita konfigurasi routing eigrp lagi

R3(config)#router eigrp 10
R3(config-router)#net 10.10.10.0 0.0.0.7
R3(config-router)#ex

Selanjutnya kita konfigurasi access lis untuk memblokir network yang kita
inginkan

R1(config)#access-list 28 deny 0.0.0.1 255.255.255.254
R1(config)#access-list 28 permit 0.0.0.0 255.255.255.254
R1(config)#router eigrp 10
R1(config-router)#distribute-list 28 in e0/0
R1(config-router)#ex

Assalamualaikum wr wb

Alhamdulillah kita masih bisa share kebali tentunya di Belajar IT bersama, kali ini kita akan melanjutkan Eigrp. kali ini  Filter Network yang masuk dengan EIGRP, kalo kemarin kita menggunakan loopback 7 interface, kali ini hanya 2 interface di router 3. kita hanya menggunakan 2 buah router.

nantinya network 10.10.10.1, dan 10.10.10.2 tidak bisa ke router 1, pertama kita konfiugrasi ip addressnya
R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int e0/0
R1(config-if)#no sh
R1(config-if)#ip add 12.12.12.1 255.255.255.0
R1(config-if)#ex

R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#int e0/0
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#no sh
R2(config-if)#int e0/1
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#no sh
R2(config-if)#ex

R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#int e0/0
R3(config-if)#no sh
R3(config-if)#ip add 23.23.23.3 255.255.255.0
R3(config-if)#ex

kemudian kita konfiguasi routing eigrp supaya bisa terhubung

R1(config)#router eigrp 10
R1(config-router)#no au
R1(config-router)#net 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.0 0.0.0.255
R1(config-router)#ex
R2(config)#router eigrp 10
R2(config-router)#no au
R2(config-router)#net 2.2.2.2 0.0.0.0
R2(config-router)#net 12.12.12.0 0.0.0.255
R2(config-router)#net 23.23.23.0 0.0.0.255
R2(config-router)#ex
R3(config)#router eigrp 10
R3(config-router)#no au
R3(config-router)#net 23.23.23.0 0.0.0.255
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#ex

selanjutnya kita tambahkan interface loopback di router 3

R3(config)#int lo1
R3(config-if)#ip add 10.10.10.1 255.255.255.255
R3(config-if)#int lo2
R3(config-if)#ip add 10.10.10.2 255.255.255.255

konfiurasi lagi routing eigrpnya

R3(config)#router eigrp 1

R3(config-router)#net 10.10.10.0 0.0.0.3

R3(config-router)#exi

kemudian kita cek tabel routingnya

R1#sh ip ro
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
       a - application route
       + - replicated route, % - next hop override

Gateway of last resort is not set

      1.0.0.0/32 is subnetted, 1 subnets
C        1.1.1.1 is directly connected, Loopback0
      2.0.0.0/32 is subnetted, 1 subnets
D        2.2.2.2 [90/409600] via 12.12.12.2, 00:04:24, Ethernet0/0
      3.0.0.0/32 is subnetted, 1 subnets
D        3.3.3.3 [90/435200] via 12.12.12.2, 00:01:43, Ethernet0/0
      10.0.0.0/32 is subnetted, 2 subnets
D        10.10.10.1 [90/435200] via 12.12.12.2, 00:00:21, Ethernet0/0
D        10.10.10.2 [90/435200] via 12.12.12.2, 00:00:21, Ethernet0/0
      12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        12.12.12.0/24 is directly connected, Ethernet0/0
L        12.12.12.1/32 is directly connected, Ethernet0/0
      23.0.0.0/24 is subnetted, 1 subnets
D        23.23.23.0 [90/307200] via 12.12.12.2, 00:04:19, Ethernet0/0

kemudian kita konfigurasi access list untuk memblokir network yang kita inginkan

R1(config)#ip access-list standard 15
R1(config-std-nacl)#deny 10.10.10.0 0.0.0.3
R1(config-std-nacl)#permit any
R1(config-std-nacl)#exi

masuk lagi ke eigrp untuk menerapkan

R1(config)#router eigrp 10
R1(config-router)#distribute-list 15 in e0/0
R1(config-router)#exi

sekarang kita cek kembali tabel routingnya

R1# sh ip ro
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
       a - application route
       + - replicated route, % - next hop override

Gateway of last resort is not set

      1.0.0.0/32 is subnetted, 1 subnets
C        1.1.1.1 is directly connected, Loopback0
      2.0.0.0/32 is subnetted, 1 subnets
D        2.2.2.2 [90/409600] via 12.12.12.2, 00:21:29, Ethernet0/0
      3.0.0.0/32 is subnetted, 1 subnets
D        3.3.3.3 [90/435200] via 12.12.12.2, 00:18:48, Ethernet0/0
      12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        12.12.12.0/24 is directly connected, Ethernet0/0
L        12.12.12.1/32 is directly connected, Ethernet0/0
      23.0.0.0/24 is subnetted, 1 subnets
D        23.23.23.0 [90/307200] via 12.12.12.2, 00:21:24, Ethernet0/0
