O multicast é suportado em VPNs habilitadas para multicast (mVPN). O mVPN usa os mesmos conceitos de Virtual Routing and Forwarding (VRF) que as redes VPN de Camada 3 unicast usam.
Esta imagem mostra o encaminhamento multicast intra-VRF (usando o perfil 0).
Imagem 1. Fluxo de pacote multicast para MVRF intranet
O multicast depende do RPF (Reverse Path Forwarding). Isso também se aplica ao tráfego multicast entre VRF. Isso significa que, para que o multicast flua de um VRF para outro VRF, é necessário ter um VRF para RPF para a origem do tráfego multicast para outro VRF. Portanto, a rota para a origem multicast precisa estar disponível na tabela de roteamento VRF do receptor no roteador PE. Há duas maneiras de garantir o sucesso do RPF no contexto do VRF.
Um roteador PE não anuncia novamente uma rota VPN. Se um roteador PE recebeu uma rota VPN de um roteador PE remoto e a importou para o VRF 1, ele não poderá exportar esse prefixo de VPN do VRF 1 para o VRF 2 localmente. Não importa se há uma rota de importação de destino de rota do VRF 1 para o VRF 2 localmente neste roteador PE ou não, a importação para o VRF 2 não ocorre.
O multicast tem tudo a ver com o sucesso do RPF. Fique sempre de olho no RPF. Para que o multicast extranet funcione, o RPF deve ser de um VRF a outro, do receptor ao VRF de origem. Portanto, deve haver uma rota unicast para a origem no VRF receptor de volta para o VRF de origem.
Lmdt: Árvore de distribuição multicast rotulada
O Cisco IOS XE também suporta mVPN extranet. No passado, o IOS (-XE) introduziu dois esquemas para alcançar o mVPN extranet. São referidas como opção 1 e opção 2. O IOS-XR suporta extranet com os mesmos esquemas.
Opção 1: O Multicast Virtual Routing and Forwarding (MVRF) de origem está no MVRF receptor. Isso significa que o VRF (VRF de origem) no roteador PE de entrada para o tráfego multicast também é configurado no roteador PE de saída com os destinos de rota apropriados.
Veja a Imagem 2. Mostra o fluxo de pacotes multicast para a Opção 1.
Imagem 2. Fluxo de pacote multicast para a Opção de extranet 1.
O tráfego multicast atravessa a rede central e usa o encapsulamento do MVRF de origem.
Opção 2: O receptor MVRF está no MVRF de origem. Isso significa que o VRF (receptor VRF) no roteador PE de saída para o tráfego multicast também é configurado no roteador PE de entrada com os destinos de rota apropriados.
Veja a Imagem 3. Mostra o fluxo de pacotes multicast para a Opção 2.
Imagem 3. Fluxo de pacote multicast para a Opção de extranet 2.
O tráfego multicast atravessa a rede central e usa o encapsulamento do MVRF de origem e do MVRF de receptor. Portanto, o tráfego multicast usa duas vezes a quantidade de largura de banda na rede central.
Há uma terceira opção, uma solução híbrida entre a Opção 1 e a Opção 2.
Opção 3: Um MVRF de transporte é usado. O roteador de entrada PE extranets o tráfego multicast do VRF de origem para o VRF de transporte. O roteador PE de saída extranet o tráfego multicast do VRF de transporte para o VRF receptor. Esse MVRF de transporte não tem interfaces para o cliente associadas a ele.
Imagem 4. Fluxo de pacote multicast para extranet usando um terceiro VRF, o VRF de transporte.
Todos os perfis têm suporte baseado em RPL.
Somente os perfis que usam o protocolo multicast core-tree (perfil 0, 3 e 11) suportam mVPN extranet baseada em RIB.
Todos os perfis suportam suporte baseado em RPL e em RIB, exceto os perfis que usam a sinalização do cliente com BGP (por exemplo, perfis 2, 11, ...). Estes últimos suportam apenas a opção 2 de forma especial. O exemplo 2.2 ilustra isso.
Procure aqui uma visão geral e uma configuração para os diferentes perfis: Configurar perfis mVPN no Cisco IOS-XR
Observe as flags EX ou Extranet nas entradas Multicast RIB (MRIB). Eles estão presentes no VRF de origem e de receptor, nas entradas multicast e nas interfaces.
O perfil 0 usa o MDT padrão, com sinalização de multicast PIM na parte inferior e na sobreposição (contexto VRF).
Esse perfil suporta as Opções 1 e 2 (e, portanto, 3).
A imagem 5 mostra o tráfego multicast intra-VRF, VRF 1 para VRF 1.

Não há estado para (10.0.0.15, 232.1.1.3) em PE de entrada, PE2, em VRF um, se VRF um estiver presente mesmo no roteador PE de entrada, PE2.
O método alternativo ao método baseado em RIB é o método baseado em RPL. Isso significa que uma política de rota é usada para alterar o RPF. Veja o exemplo 2.1 para um exemplo dessa política de rota RPF.
Esta é a abordagem baseada em RIB.
Image 7 Profile 0 - Option 2 (Perfil de imagem 0 - Opção 2) O receptor MVRF está no MVRF de origem
Um Route-Target é usado para importar duas rotas de VRF para VRF uma no PE receptor, PE3.
O PE de entrada, PE2, precisa de uma rota estática no VRF um (VRF de receptor) apontado para o VRF dois (VRF de origem) para que o RPF seja bem-sucedido no roteador PE de entrada, PE2.

Não há necessidade de redistribuir essa rota estática no BGP. Essa rota é anunciada no VRF dois, o VRF de origem. O roteador PE de saída, PE3, recebe essa rota porque é anunciado pelo roteador PE de entrada, PE1, no VRF dois com Route-Target 65000:3333, que é importado para o VRF um em PE3. A rota estática é necessária para que o RPF seja bem-sucedido em VRF no roteador PE de entrada, PE2.
O tráfego multicast usa o MDT do VRF um para cruzar a rede central.

Imagem 8. Perfil 0 - Opção 3 Um MVRF de transporte é usado
O MVRF de transporte não precisa de nenhuma interface. No entanto, tudo o resto precisa estar lá: a configuração do VRF, a configuração do BGP, a configuração do roteamento multicast e a configuração do PIM do roteador.
A configuração da opção 1 está no PE de saída, PE1 e a configuração da opção 2 está no PE de entrada, PE2.

Há apenas um roteador PE envolvido. Ter uma rota de volta no VRF receptor para o VRF de origem é o único requisito aqui para a solução baseada em RIB.
Uma solução é fazer com que o VRF um (VRF de origem) importe as rotas do VRF dois (VRF de receptor) usando o Route-Target apropriado.

O perfil 14 usa MDT particionado, com sinalização multicast mLDP na parte inferior e sinalização BGP (cliente) na sobreposição (contexto VRF).
Este perfil suporta a opção 1.
As Opções 2 e 3 podem ser feitas para trabalhar com um truque de roteamento.
A imagem 10 mostra o tráfego multicast intra-VRF, VRF um para VRF um.

Observe que a interface GE0/0/0/1 está no VRF um.
Essa solução não pode funcionar manipulando as instruções de importação e exportação para os destinos da rota ou por uma alteração da política de rota usada somente pelo RPF.
Um truque ajuda a corrigir o RPF no roteador PE de entrada. O truque é adicionar uma rota estática no VRF do receptor e apontá-la para o VRF de origem no roteador PE de entrada.
A rota estática anuncia o endereço de origem no VRF receptor. Essa rota estática é marcada com um novo Route-Target exclusivo no BGP para que essa rota possa ser diferenciada da mesma rota anunciada no VRF de origem. Isso evita a importação da rota estática do VRF receptor no PE de entrada para o VRF receptor dos outros roteadores PE, o que causa um problema de roteamento.

O VRF de transporte não precisa de nenhuma interface. No entanto, tudo o resto precisa estar lá: a configuração do VRF, a configuração do BGP, a configuração do roteamento multicast e a configuração do PIM do roteador.
A configuração da opção 1 está no PE de saída, PE1 e a configuração da opção 2 está no PE de entrada, PE2. PE1:
