Introdução

Este documento mostra como configurar o Multiprotocol Label Switching (MPLS) da Virtual Private Network (VPN) em Modo de Transferência Assíncrona (Asynchronous Transfer Mode) com roteadores Cisco 7500 como Label Edge Routers (LERs) e roteadores LightStream 1010 como Label Switch Routers (LSRs). Dois roteadores conectados por Ethernet, cada um em um site de cliente remoto, são parte de uma VPN. Neste documento, examinamos as configurações de dispositivo fim-a-fim e os comandos show úteis.

Configurar

Nesta seção, você encontrará informações para configurar os recursos descritos neste documento.

Diagrama de Rede

Este documento utiliza a seguinte configuração de rede:

vpn-mpls-1.gif

Descrição da rede

A configuração atual contém estes elementos na terminologia VPN:

  • CE = Roteador de borda do cliente

  • PE = Roteador de borda do provedor

  • P=Roteador do provedor

A configuração atual contém estes elementos na terminologia MPLS:

  • LER = Label Edge Router

  • LSR = Label Switch Router (Roteador de switch de rótulo)

  • TDP/LDP = Tag Distribution Protocol/Label Distribution Protocol (Protocolo de Distribuição de Tag/Protocolo de Distribuição de Label)

Configurações

Este documento utiliza as seguintes configurações:

  • PE1 e PE2 são os LERs em nossa rede ATM.

  • P1 e P2 são os LSRs.

  • CE1 e CE2 são roteadores de borda do cliente que não reconhecem e não executam VPN ou MPLS.

  • CE1 e CE2 são Ethernet conectadas a PE1 e PE2 respectivamente e executam o Routing Information Protocol (RIP).

  • PE1, PE2, P1 e P2 fazem o OSPF (Open Shortest Path First) e estão todos na área 0. O OSPF é o IGP (Interior Gateway Protocol) usado na rede ATM. A comutação de tag é usada nas interfaces ATM em todos os quatro dispositivos ATM. O protocolo TDP atribui tags às rotas OSPF.

  • PE1 e PE2 são pares de Protocolo de Gateway de Borda Multiprotocolo (MP-BGP).

  • As rotas RIP são redistribuídas no MP-BGP. Rotas MP-BGP redistribuídas no RIP nos roteadores PE1 e PE2.

  • A configuração mantém tabelas de roteamento VRF separadas nos roteadores PE1 e PE2.

  • O nome da VPN usada neste exemplo é NOVO.
