Lab 60 - OSPF Redistribution Connected

Pada lab ini kita akan belajar melakukan redistribution connected network ke OSPF. Berikut topologi yang akan kita gunakan pada lab ini

Gambar 1 Topologi jaringan OSPF

Kita hapus dulu konfigurasi static route dan redistribution yang sebelumnya kita lakukan di R2

R2(config)#no ip route 11.11.11.1 255.255.255.255 12.12.12.1
R2(config)#router ospf 1
R2(config-router)#no redistribute static subnets

Pastikan R2 dan R3 tidak memiliki informasi tentang IP Loopback R1

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

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, 00:24:17, 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

Sekarang kita coba lakukan redistribute connected di R1

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

Untuk pengujian kita coba lihat tabel routing di R2 dan R3

R2(config-router)#do sh ip ro

      11.0.0.0/32 is subnetted, 6 subnets
O E2     11.11.11.1 [110/20] via 12.12.12.1, 00:00:19, Ethernet0/0
O E2     11.11.11.2 [110/20] via 12.12.12.1, 00:00:19, Ethernet0/0
O E2     11.11.11.3 [110/20] via 12.12.12.1, 00:00:19, Ethernet0/0
O E2     11.11.11.4 [110/20] via 12.12.12.1, 00:00:19, Ethernet0/0
O E2     11.11.11.5 [110/20] via 12.12.12.1, 00:00:19, Ethernet0/0
O E2     11.11.11.6 [110/20] via 12.12.12.1, 00:00:19, 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
      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 

      11.0.0.0/32 is subnetted, 6 subnets
O E2     11.11.11.1 [110/20] via 23.23.23.2, 00:00:40, Ethernet0/0
O E2     11.11.11.2 [110/20] via 23.23.23.2, 00:00:40, Ethernet0/0
O E2     11.11.11.3 [110/20] via 23.23.23.2, 00:00:40, Ethernet0/0
O E2     11.11.11.4 [110/20] via 23.23.23.2, 00:00:40, Ethernet0/0
O E2     11.11.11.5 [110/20] via 23.23.23.2, 00:00:40, Ethernet0/0
O E2     11.11.11.6 [110/20] via 23.23.23.2, 00:00:40, Ethernet0/0
      12.0.0.0/24 is subnetted, 1 subnets
O        12.12.12.0 [110/20] via 23.23.23.2, 00:25:56, 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 sudah mengetahui IP Loopback R1, perhatikan label E2 yang menyatakan bahwa route tersebut merupakan hasil redistribution dari routing protocol lain
