Projeto MPLS e OSPF – Parte 2

Depois de algum tempo… Está aí as configurações de endereçamento IP, roteamento estático e dinâmico com OSPF na topologia citada.

ROUTER FOZ

Router(config)# hostname FOZ

! CONFIGURAÇÕES DE INTERFACES

! Obs: Interface loopback é uma interface de software (sempre ativa)

FOZ(config)# interface loopback 0

FOZ(config-if)# ip address 192.168.1.1 255.255.255.0

!

FOZ(config)# interface loopback 1

FOZ(config-if)# ip address 192.168.2.1 255.255.255.0

!

FOZ(config)# interface serial 1/0

FOZ(config-if)# ip address 10.0.10.1 255.255.255.252

FOZ(config-if)# clock rate 4032000

FOZ(config-if)# no shutdown

FOZ(config-if)# exit

!

! CONFIGURAÇÕES DE ROTEAMENTO

! Obs: Rota padrão para qualquer destino que não conste na tabela de roteamento, ou seja, tudo que não tenha uma rota especificada sai pela interface 10.0.10.2

!

FOZ(config)# ip route 0.0.0.0 0.0.0.0 10.0.10.2

!

! Obs: O número 100 abaixo corresponde ao processo OSPF, esse número tem significado local não influenciando no roteamento em si, não confundir com AS !(Autonomous System)

!

FOZ(config)# router ospf 100

FOZ(config-router)# network 10.0.10.0 0.0.0.3 area 1

FOZ(config-router)# end

!

FOZ# copy running-config startup-config

ROUTER CASCAVEL

Router(config)# hostname CASCAVEL

!

CASCAVEL(config)# interface serial 1/0

CASCAVEL(config-if)# ip address 10.0.10.2 255.255.255.252

CASCAVEL(config-if)# no shutdown

!

CASCAVEL(config)# interface serial 2/0

CASCAVEL(config-if)# ip address 10.0.20.1 255.255.255.252

CASCAVEL(config-if)# clock rate 4032000

CASCAVEL(config-if)# no shutdown

CASCAVEL(config-if)# exit

!

CONFIGURAÇÕES DE ROTEAMENTO

!

Obs: Rotas estáticas: por padrão sempre são escolhidas na comutação pois tem maior prioridade ou a menor métrica do que qualquer protocolo de roteamento

!

CASCAVEL(config)# ip route 192.168.1.0 255.255.255.0 10.0.10.1

CASCAVEL(config)# ip route 192.168.2.0 255.255.255.0 10.0.10.1

!

Obs: O comando redistribute static irá informar os vizinhos sobre rotas estáticas instaladas localmente

!

CASCAVEL(config)# router ospf 100

CASCAVEL(config-router)# redistribute static

CASCAVEL(config-router)# network 10.0.10.0 0.0.0.3 area 1

CASCAVEL(config-router)# network 10.0.20.0 0.0.0.3 area 1

É isso aí… Rede convergida com OSPF agora é só partir para configuração MPLS, o que demandará muito papiro!
