Lab 62 - OSPF Redistribution EIGRP

Pada lab ini kita akan melakukan redistribute route EIGRP ke OSPF. Berikut topologi yang akan kita gunakan pada lab ini

Gambar 1 Topologi jaringan OSPF & EIGRP

Kita akan menambahkan IP Loopback pada R1 dan mengadvertise IP tersebut ke EIGRP, baru kemudia kita akan redistribute route EIGRP tersebut ke OSPF

R1(config)#int lo7
R1(config-if)#ip add 101.101.101.1 255.255.255.255

R1(config-if)#router eigrp 1
R1(config-router)#no auto         
R1(config-router)#net 101.101.101.0

R1(config-router)#router ospf 1
R1(config-router)#redistribute eigrp 1 subnets

Untuk pengujian kita coba lihat tabel routing di R2 dan R3

R2(config-router)#do sh ip ro 

      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
      100.0.0.0/32 is subnetted, 1 subnets
O E2     100.100.100.1 [110/20] via 12.12.12.1, 00:09:56, Ethernet0/0
      101.0.0.0/32 is subnetted, 1 subnets
O E2     101.101.101.1 [110/20] via 12.12.12.1, 00:00:50, Ethernet0/0

R3(config-router)#do sh ip ro

      12.0.0.0/24 is subnetted, 1 subnets
O        12.12.12.0 [110/20] via 23.23.23.2, 00:47:17, 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
      100.0.0.0/32 is subnetted, 1 subnets
O E2     100.100.100.1 [110/20] via 23.23.23.2, 00:10:18, Ethernet0/0
      101.0.0.0/32 is subnetted, 1 subnets
O E2     101.101.101.1 [110/20] via 23.23.23.2, 00:01:12, Ethernet0/0

Perhatikan bahwa R2 dan R3 sudah memiliki informasi tentang 101.101.101.1 dari hasil redistribution. Kita coba lakukan ping dari R3 ke IP tersebut

R3(config-router)#do ping 101.101.101.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 101.101.101.1, timeout is 2 seconds:

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
