Lab 46 - EIGRP Redistribution RIP

Pada lab ini ita akan belajar melakukan redistribute routing protocol RIP ke EIGRP. Berikut topologi yang akan kita gunakan pada lab ini.

Gambar 1 Topologi jaringan RIP & EIGRP

Topologi diatas merupakan topologi yang sudah kita gunakan pada lab-lab sebelumnya. Selanjutnya pada lab ini kita hanya akan menambahkan IP pada interface loopback di R1 dan mengadvertise IP tersebut ke RIP.

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.0

R1(config-if)#router rip
R1(config-router)#no auto-summary
R1(config-router)#version 2
R1(config-router)#network 1.1.1.0

Sekarang kita coba lihat tabel routing di R2 dan R3, apakah kedua router tersebut sudah memiliki informasi tentang network 1.1.1.0/24 ataukah belum

R2(config-router)#do sh ip ro

      10.0.0.0/32 is subnetted, 6 subnets
D        10.10.10.1 [90/409600] via 23.23.23.3, 00:00:35, Ethernet0/1
D        10.10.10.2 [90/409600] via 23.23.23.3, 00:00:30, Ethernet0/1
D        10.10.10.3 [90/409600] via 23.23.23.3, 00:00:24, Ethernet0/1
D        10.10.10.4 [90/409600] via 23.23.23.3, 00:00:18, Ethernet0/1
D        10.10.10.5 [90/409600] via 23.23.23.3, 00:00:13, Ethernet0/1
D        10.10.10.6 [90/409600] via 23.23.23.3, 00:00:03, Ethernet0/1
      12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        12.12.12.0/24 is directly connected, Ethernet0/0
      23.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        23.23.23.0/24 is directly connected, Ethernet0/1

R3(config-if)#do sh ip ro

      10.0.0.0/32 is subnetted, 6 subnets
C        10.10.10.1 is directly connected, Loopback0
C        10.10.10.2 is directly connected, Loopback1
C        10.10.10.3 is directly connected, Loopback2
C        10.10.10.4 is directly connected, Loopback3
C        10.10.10.5 is directly connected, Loopback4
C        10.10.10.6 is directly connected, Loopback5
      12.0.0.0/24 is subnetted, 1 subnets
D        12.12.12.0 [90/307200] via 23.23.23.2, 00:02:49, Ethernet0/0
      23.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        23.23.23.0/24 is directly connected, Ethernet0/0

Perhatikan bahwa R2 dan R3 belum mengetahui informasi tentang network 1.1.1.0/24, hal ini dikarenakan network ini berada di jaringan RIP sedangkan R2 dan R3 berada di jaringan EIGRP. Untuk mengatasi hal ini, kita harus melakukan redistribution di R1

R1(config-if)#router eigrp 1
R1(config-router)#redistribute rip metric 1 1 1 1 1

Sekarang kita coba lihat lagi tabel routing di R2 dan R3

R2(config-router)#do sh ip ro

      1.0.0.0/24 is subnetted, 1 subnets
D EX     1.1.1.0 [170/2560025856] via 12.12.12.1, 00:00:44, Ethernet0/0
      10.0.0.0/32 is subnetted, 6 subnets
D        10.10.10.1 [90/409600] via 23.23.23.3, 00:04:51, Ethernet0/1
D        10.10.10.2 [90/409600] via 23.23.23.3, 00:04:46, Ethernet0/1

D        10.10.10.6 [90/409600] via 23.23.23.3, 00:04:19, Ethernet0/1
      12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        12.12.12.0/24 is directly connected, Ethernet0/0
      23.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        23.23.23.0/24 is directly connected, Ethernet0/1

R3(config-router)#do sh ip ro                      

      1.0.0.0/24 is subnetted, 1 subnets
D EX     1.1.1.0 [170/2560051456] via 23.23.23.2, 00:01:14, Ethernet0/0

      12.0.0.0/24 is subnetted, 1 subnets

C        23.23.23.0/24 is directly connected, Ethernet0/0

Perhatikan bahwa saat ini R2 dan R3 sudah memiliki informasi tentang network 1.1.1.0/24. Perhatikan label EX didepan route tersebut menandakan bahwa route tersebut didapat dari hasil redistribution dari routing protocol lain
