Belajar IT Bersama: konfigurasi Eigrp Summarization

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
       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

      3.0.0.0/24 is subnetted, 1 subnets
D        3.3.3.0 [90/2323456] via 12.12.12.2, 00:01:27, Serial2/0
      10.0.0.0/32 is subnetted, 7 subnets

D        10.10.10.6 [90/2323456] via 12.12.12.2, 00:00:43, Serial2/0
D        10.10.10.7 [90/2323456] via 12.12.12.2, 00:00:40, Serial2/0
      12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        12.12.12.0/24 is directly connected, Serial2/0
L        12.12.12.1/32 is directly connected, Serial2/0
      23.0.0.0/24 is subnetted, 1 subnets
D        23.23.23.0 [90/2195456] via 12.12.12.2, 01:31:41, Serial2/0
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
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 12.12.12.2 to network 0.0.0.0

D*    0.0.0.0/0 [90/2323456] via 12.12.12.2, 00:00:04, Serial2/0

R1(config)#

coba kita ping ke antar network
