Configuração RIP em GNS3

RIP - Lab com múltiplas tarefas:

- Configuração de Frame-Relay nos Routers:

R1(config): interface Serial0/0
R1(config-if): no shutdown
R1(config-if): no ip address
R1(config-if): encapsulation frame-relay
R1(config-if): no frame-relay inverse-arp

R1(config): interface Serial0/0.12 point-to-point
R1(config-if): ip address 172.12.123.1 255.255.255.0
R1(config-if): frame-relay interface-dlci 102

R1(config): interface Serial0/0.13 point-to-point
R1(config-if): ip address 172.12.13.1 255.255.255.0
R1(config-if): frame-relay interface-dlci 103

R2(config): interface Serial0/0
R2(config-if): no shutdown
R2(config-if): no ip address
R2(config-if): encapsulation frame-relay
R2(config-if): no frame-relay inverse-arp

R2(config): interface Serial0/0.21 point-to-point
R2(config-if): ip address 172.12.123.2 255.255.255.0
R2(config-if): frame-relay interface-dlci 201

R3(config): interface Serial0/0
R3(config-if): no shutdown
R3(config-if): no ip address
R3(config-if): encapsulation frame-relay
R3(config-if): no frame-relay inverse-arp

R3(config): interface Serial0/0.31 point-to-point
R3(config-if): ip address 172.12.13.2 255.255.255.0
R3(config-if): frame-relay interface-dlci 301

- Configuração do Frame-Relay Switch:

- Configuração básica de RIP:

R1(config): router rip
R1(config-router): version 2
R1(config-router): no auto-summary
R1(config-router): network 172.12.0.0
R1(config-router): network 1.0.0.0

R2(config): router rip
R2(config-router): version 2
R2(config-router): no auto-summary
R2(config-router): network 172.12.0.0
R2(config-router): network 2.0.0.0

R3(config): router rip
R3(config-router): version 2
R3(config-router): no auto-summary
R3(config-router): network 172.12.0.0
R3(config-router): network 3.0.0.0

- Configuração de timers:

R1(config): router rip
R1(config-router): timers basic 30 180 180 240

R2(config): router rip
R2(config-router): timers basic 30 180 180 240

R3(config): router rip
R3(config-router): timers basic 30 180 180 240

- Configuração de "triggered updates":

R1(config): interface serial 0/0.12
R1(config-if): ip rip triggered
R1(config): interface serial 0/0.13
R1(config-if): ip rip triggered

R2(config): interface serial 0/0.201
R2(config-if): ip rip triggered

R3(config): interface serial 0/0.301
R3(config-if): ip rip triggered

- Configuração de neighbours (unicast):

Nota: O comando "passive" impede o envio de broadcasts/multicasts.

R1(config): router rip
R1(config-router): neighbor 172.12.123.2
R1(config-router): neighbor 172.12.13.2
R1(config-router): passive interface serial 0/0.12
R1(config-router): passive interface serial 0/0.13
R1(config-router): passive interface loopback 1

R2(config): router rip
R2(config-router): neighbor 172.12.123.1
R2(config-router): passive interface serial 0/0.201
R2(config-router): passive interface loopback 2

R3(config): router rip
R3(config-router): neighbor 172.12.13.1
R3(config-router): passive interface serial 0/0.301
R3(config-router): passive interface loopback 3

- Criar Default Route que seja anunciada pelo RIP no R1:

R1(config): ip route 0.0.0.0 0.0.0.0 195.23.10.2
R1(config): router rip
R1(config-router): default-information originate

- Configurar sumarização no R3:

R3(config): interface serial 0/0.301
R3(config-if): ip summary-address rip 10.30.0.0 255.255.252.0

- Criar link de backup entre R0 e R2 por forma a evitar o Load-Balancing entre os 2 links:

R0(config): ip access-list standard RIP_BACKUP_OFFSET
R0(config-std-nacl): permit any

R0(config): router rip
R0(config-router): offset-list RIP_BACKUP_OFFSET in 2 Serial0/1
R0(config-router): offset-list RIP_BACKUP_OFFSET out 2 Serial0/1
