Lab 1. Mutual Redistribution

Pada postingan kali ini kita akan belajar saling redistribute berbagai macam routing protocol. Lebih jelasnya perhatikan topologi diatas.

Konfigurasi R1

R1#conf
R1(config)#interface se0/0
R1(config-if)#ip address 12.12.12.1 255.255.255.0
R1(config-if)#no shu
R1(config-if)#ex

R1(config)#interface lo0
R1(config-if)#ip address 1.1.1.1 255.255.255.255
R1(config-if)#ex

R1(config)#router rip
R1(config-router)#ver 2
R1(config-router)#network 12.12.12.1
R1(config-router)#network 1.1.1.1
R1(config-router)#no au

Konfigurasi R2

R2(config-if)#ex

R2(config)#router rip

R2(config-router)#ver 2

R2(config-router)#network 12.12.12.2

R2(config-router)#redistribute ospf 1 metric 1

R2(config-router)#ex

R2(config)#router ospf 1

R2(config-router)#network 23.23.23.2 0.0.0.0 area 0

R2(config-router)#redistribute rip subnets

R2(config-router)#

Konfigurasi R3

R3#configure

R3(config)#interface fa0/0

R3(config-if)#ip address 23.23.23.3 255.255.255.0

R3(config-if)#no au

R3(config)#interface fa0/1

R3(config-if)#ip address 34.34.34.3 255.255.255.0

R3(config-if)#ex

R3(config)#router ospf 1

R3(config-router)#redistribute eigrp 1 subnets

R3(config-router)#network 23.23.23.3 0.0.0.0 area 0

R3(config-router)#ex

R3(config)#router eigrp 1

R3(config-router)#network 34.34.34.3 0.0.0.0

R3(config-router)#redistribute ospf 1 metric 1 1 1 1 1

Konfigurasi R4

R4#configure

R4(config)#interface fa0/1

R4(config-if)#ip address 34.34.34.4 255.255.255.0

R4(config-if)#no shu

R4(config-if)#ex

R4(config)#interface se0/0

R4(config-if)#ip address 45.45.45.4 255.255.255.0

R4(config-if)#no sh

R4(config-if)#ex

R4(config)#router eigrp 1

R4(config-router)#network 34.34.34.4 0.0.0.0

R4(config-router)#redistribute ospf 2 metric 1 1 1 1 1

R4(config-router)#no au

R4(config-router)#ex

R4(config)#router ospf 2

R4(config-router)#network 45.45.45.4 0.0.0.0 area 0

R4(config-router)#redistribute eigrp 1 subnets

Konfigurasi R5

R5(config)#interface se0/0

R5(config-if)#ip address 45.45.45.5 255.255.255.0

R5(config-if)#no sh

R5(config-if)#ex

R5(config)#interface fa0/0

R5(config-if)#ip address 56.56.56.5 255.255.255.0

R5(config-if)#no sh

R5(config-if)#ex

R5(config)#router os 3

R5(config-router)#network 45.45.45.5 0.0.0.0 area 0

R5(config-router)#redistribute static subnets

R5(config-router)#default-information originate always

R5(config-router)#ex

R5(config)#interface lo0

R5(config-if)#ip address 5.5.5.5 255.255.255.255

Konfigurasi R6

R6(config)#interface fa0/0
R6(config-if)#ip address 56.56.56.6 255.255.255.0
R6(config-if)#no sh
R6(config-if)#ex

R6(config)#interface lo0
R6(config-if)#ip address 8.8.8.8 255.255.255.255

Verifikasi

Kemudian tambahkan IP Loopback1 55.55.55.5 di R5, kemduian lakukan redistribute connected di di R3 melalui router ospf

R5(config)#interface lo1

R5(config-if)#ip address 55.55.55.5 255.255.255.255

R5(config-if)#ex

R5(config)#router os 3

R5(config-router)#redistribute connected subnets

Cek routing Tabel di router paling ujung yakni R1, atau test PING

Berhasil

Jika di pada R1, R2, R3 dan R4 ketika di sh ip route, maka akan nampak ip 8.8.8.8 pada routing tabelnya, namun ketika di ping hasilnya no reply. Solusinya adalah tambahkan konfigurasi ini di R5.

R5(config)#ip nat inside source list 1 interface FastEthernet0/0 overload

R5(config)#access-list 1 permit any

R5(config-if)#interface FastEthernet0/0

R5(config-if)#ip nat outside

R5(config-if)#interface Serial0/0

R5(config-if)#ip nat inside

Test PING
