Exemplo: configuração de PBB com EVPN de casa única
Este exemplo mostra como integrar a ponte de backbone (PBB) do provedor com a VPN Ethernet (EVPN). Com essa integração, as operações de plano de controle no núcleo são simplificadas, fornecendo melhorias mais rápidas de convergência e escalabilidade do que a EVPN regular. Os aplicativos PBB-EVPN incluem a Interconexão de Data Center (DCI) e os serviços Ethernet E-LAN da operadora.
Requisitos
Este exemplo usa os seguintes componentes de hardware e software:
Três dispositivos de borda de provedor (PE) cada um conectados a sites de clientes de um único lar.
Quatro dispositivos de borda do cliente (CE) que são de casa única para os dispositivos de PE.
Junos OS Release 17.2R1 ou posterior em todos os roteadores PE.
Antes de começar:
Configure as interfaces do dispositivo.
Configure um IGP, como o OSPF, em todos os dispositivos PE.
Estabeleça uma sessão BGP interna entre os dispositivos PE.
Habilite o RSVP nos dispositivos de PE.
Configure o MPLS e os caminhos comuados por rótulos (LSPs) entre os dispositivos PE.
Visão geral e topologia
A partir do Junos OS Release 17.2R1, o PBB é integrado à VPN Ethernet (EVPN) para permitir uma redução significativa no aprendizado do plano de controle em todo o núcleo, permitindo que um grande número de serviços de Camada 2, como a conectividade de data center, transite pela rede de forma simplificada.
Em uma rede PBB-EVPN, o dispositivo de ponte de núcleo de backbone (BCB) no núcleo do PBB é substituído por MPLS, mantendo as propriedades de escala de serviço da ponte de borda do backbone PBB (BEB). O componente B (instância de roteamento do provedor) é sinalizado usando sinalização EVPN BGP e encapsulado dentro do MPLS usando dispositivos de borda de provedor (PE) e provedor (P). Assim, a PBB-EVPN combina a vasta propriedade de escalonamento do PBB com a simplicidade de uma rede núcleo MPLS básica tradicional, resultando em uma redução significativa na quantidade de informações de estado em toda a rede, em oposição ao PBB regular.

Na Figura 1, o PBB é integrado à EVPN, onde os dispositivos CE são de casa única para dispositivos PE1, PE2 e PE3.
