Konfigurasi EIGRP - Default Route - Summary Address

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)#
