Lab 18. OSPF - Redistribution

Pertama kita konfigurasikan single area ospf pada semua router

R1(config)#router ospf 1
R1(config-router)#router-id 1.1.1.1
R1(config-router)#network 1.1.1.1 0.0.0.0 area 0 R1(config-router)#network 12.12.12.0 0.0.0.255 area 0

R2(config)#router ospf 2
R2(config-router)#router-id 2.2.2.2
R2(config-router)#network 12.12.12.0 0.0.0.255 area 0
R2(config-router)#network 23.23.23.0 0.0.0.255 area 0
R2(config-router)#network 2.2.2.2 0.0.0.0 area 0

R3(config)#router ospf 3
R3(config-router)#router-id 3.3.3.3
R3(config-router)#network 23.23.23.0 0.0.0.255 area 0
R3(config-router)#network 3.3.3.3 0.0.0.0 area 0

Tambahkan Loopback pada R1 yang nantinya loopback ini akan dituju oleh router lain secara static.

R1(config)#int lo1
R1(config-if)#ip address 10.10.10.1 255.255.255.255

Tambahkan Loopback pada R2 juga

R2(config)#int lo1
R2(config-if)#ip address 20.20.20.1 255.255.255.255
R2(config-if)#int lo2
R2(config-if)#ip address 20.20.20.2 255.255.255.255
R2(config-if)#int lo3
R2(config-if)#ip address 20.20.20.3 255.255.255.255

Advertise network 20.20.20.1 ke EIGRP

R2(config)#router eigrp 1
R2(config-router)#network 20.20.20.1 0.0.0.0
R2(config-router)#no auto-summary

Advertise network 20.20.20.0 ke ripv2

R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#network 20.20.20.0
R2(config-router)#no auto-summary

Buat static route untuk ke lopback R1

R2(config)#ip route 10.10.10.1 255.255.255.255 12.12.12.1

Redistribute kan EIGRP, RIP, STATIC ROUTE, dan Connected

R2(config)#router ospf 2
R2(config-router)#redistribute eigrp 1 subnets
R2(config-router)#redistribute rip subnets
R2(config-router)#redistribute static subnets
R2(config-router)#redistribute connected subnets

Cek tabel routingnya

R3(config)#do sh ip route
1.0.0.0/32 is subnetted, 1 subnets
O 1.1.1.1 [110/21] via 23.23.23.2, 00:01:12, Ethernet0/0
2.0.0.0/32 is subnetted, 1 subnets
O 2.2.2.2 [110/11] via 23.23.23.2, 00:01:12, Ethernet0/0
3.0.0.0/32 is subnetted, 1 subnets
C 3.3.3.3 is directly connected, Loopback0
10.0.0.0/32 is subnetted, 1 subnets
O E2 10.10.10.1 [110/20] via 23.23.23.2, 00:01:12, Ethernet0/0
12.0.0.0/24 is subnetted, 1 subnets
O 12.12.12.0 [110/20] via 23.23.23.2, 00:01:12, Ethernet0/0
20.0.0.0/32 is subnetted, 3 subnets
O E2 20.20.20.1 [110/20] via 23.23.23.2, 00:01:12, Ethernet0/0
O E2 20.20.20.2 [110/20] via 23.23.23.2, 00:01:12, Ethernet0/0
O E2 20.20.20.3 [110/20] via 23.23.23.2, 00:01:12, 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
L 23.23.23.3/32 is directly connected, Ethernet0/0

Bisa kita lihat network dengan routing protokol yang berbeda telah muncuk di routing table R3, so jadi fungsi  redistribute adalah menghubungkan protokol routing yang berbeda.
