Visão geral do VPLS Label Switched Multicast (LSM)
O VPLS emula serviços de LAN através de um núcleo de Multiprotocol Label Switching (MPLS). Uma malha completa de pseudofios (PWs) ponto-a-ponto (P2P) é configurada entre todos os roteadores da Borda do Provedor (PE) que participam de um domínio VPLS para fornecer emulação de VPLS. O tráfego de broadcast, multicast e unicast desconhecido é enviado em um domínio VPLS para todos os PEs. A replicação de entrada é usada para enviar esse tráfego inundado em cada PWs P2P para todos os roteadores PE remotos que fazem parte do mesmo domínio VPLS.
Desvantagens da replicação de entrada
- A replicação de entrada é ineficiente em termos de largura de banda porque o mesmo pacote pode ser enviado várias vezes sobre o mesmo link para cada PW P2P.
- A replicação de ingresso pode resultar em um desperdício significativo da largura de banda do link quando há tráfego pesado de VPLS de broadcast e multicast.
- A replicação de entrada também exige muitos recursos, pois o roteador PE de entrada suporta toda a carga da replicação.
Recursos de VPLS LSM
O VPLS é uma tecnologia L2VPN de provedor de serviços amplamente implantada que também é usada para transporte multicast. Embora a tecnologia L2 permita que o snooping seja usado para otimizar a replicação do tráfego multicast em pseudofios L2, o núcleo permanece independente do tráfego multicast. Como resultado, várias cópias do mesmo fluxo passam pelas redes centrais. Para atenuar essa ineficiência, emparelhe o LSM com o VPLS para introduzir árvores multicast LSM sobre o núcleo. No Cisco IOS-XR Software Release 5.1.0, o Cisco ASR 9000 Series implementa VPLS LSM com árvores inclusivas de P2MP-TE (Point-to-Multipoint Traffic Engineering). Terminais VPLS são automaticamente descobertos e árvores P2MP-TE são configuradas com o uso de Resource Reservation Protocol Traffic Engineering (RSVP-TE) sem intervenção operacional.
- O LSM do VPLS supera as desvantagens da replicação de entrada.
- A solução LSM VPLS emprega LSPs P2MP no núcleo MPLS para transportar tráfego de broadcast, multicast e unicast desconhecido para um domínio VPLS.
- Os LSPs P2MP permitem a replicação na rede MPLS no nó ideal e minimizam a quantidade de replicação de pacotes na rede.
- A solução LSM VPLS envia apenas tráfego VPLS inundado sobre LSPs P2MP.
- O tráfego VPLS unicast ainda é enviado sobre PWs P2P. O tráfego enviado por PWs de acesso continua a ser enviado com replicação de entrada.
- Os PWs P2MP são unidirecionais, ao contrário dos PWs P2P, que são bidirecionais.
- A solução VPLS LSM envolve a criação de um PW P2MP por domínio VPLS para emular um serviço P2MP VPLS para PWs centrais no domínio VPLS.
- O VPLS LSM é suportado no Cisco IOS XR Release 5.1.0 e posterior.
Restrições de VPLS LSM
- A funcionalidade do Cisco IOS-XR Release 5.1.0 VPLS LSM suporta apenas árvores P2MP-TE de Engenharia de Tráfego MPLS configuradas com RSVP-TE.
- Um PW P2MP pode ser sinalizado com o protocolo BGP somente no Cisco IOS-XR Release 5.1.0. Nesta primeira fase, os PEs remotos que participam do domínio VPLS são descobertos automaticamente com a Descoberta Automática BGP (BGP-AD).
- A sinalização LDP estática não é suportada no Cisco IOS XR Release 5.1.0.
Aprendizado de Controle de Acesso ao Meio (MAC - Media Access Control)
O aprendizado de MAC no PE de folha para um quadro que chega no PW P2MP é feito como se o quadro fosse recebido no PW P2P levando ao PE de raiz para esse PW P2MP. Nesta imagem, o MAC Learning em PE-2 para quadros que chegam ao P2MP PW LSP enraizado em PE-1 é feito como se o quadro chegasse ao P2P PW entre PE-1 e PE-2. O plano de controle L2VPN é responsável por programar as informações de disposição do VPLS com informações P2P PW para aprendizagem MAC na disposição P2MP LSP.
Suporte a Internet Group Management Protocol Snooping (IGMPSN)
O Internet Group Management Protocol (IGMP) Snooping (IGMPSN) é suportado no início e no fim da árvore P2MP em um domínio de bridge que participa do LSM VPLS. Isso permite que o tráfego multicast IGMPSN em um PWs de instância de encaminhamento virtual (VFI) se beneficie da otimização de recursos fornecida por LSPs P2MP. Se o IGMPSN estiver habilitado em um domínio de bridge com um ou mais PWs de VFI participando do LSM do VPLS, todo o tráfego multicast da camada dois (L2) será enviado pelo P2MP P-tree Head associado ao domínio de bridge. As rotas multicast L2 são usadas para encaminhar o tráfego para receptores locais, pontos de fluxo Ethernet (EFPs), PWs de acesso e PWs de VFI que não participam do LSM do VPLS.
Quando o IGMPSN é habilitado em um domínio de bridge que é uma extremidade LSP P2MP, a disposição otimizada do tráfego multicast L2 recebido no LSP P2MP é feita para receptores locais (ou seja, Portas de Bridge (BPs) de Circuito de Conexão (AC) e BPs de PW de acesso).
Escala suportada
O Cisco IOS XR Release 5.1.0 suporta um máximo de 1000 Túneis P2MP ou 1000 PWs P2MP por roteador Head/Tail.

Exemplo de topologia e configuração
Os túneis P2MP são autodescobertos. Túneis P2MP estáticos não são suportados.
Configurações de túnel estático não são usadas. A configuração automática do túnel P2MP deve ser ativada em todos os roteadores PE e também em um roteador P se ele atuar como um nó de geração. Um nó bud é um roteador de ponto médio e de extremidade traseira ao mesmo tempo.
Um exemplo de topologia com configuração é mostrado aqui. Nessa topologia, os PWs P2MP são criados entre os três PEs e um roteador P que atua como um nó de geração. Todos os três roteadores PE atuam como Head (para tráfego de entrada) e Tail (para tráfego de saída).

Identificar e Solucionar Problemas do LSM do VPLS
Problemas comuns de configuração
As causas mais comuns de problemas P2MP no L2VPN são mostradas aqui.
- A configuração de BGP para LSM é exatamente a mesma que para BGP-AD. Certifique-se de exportar/importar rotas da família de endereços l2vpn vpls-vpws configurando address-family l2vpn vpls-vpws para vizinhos BGP.
- Há erros de configuração de MPLS e multicast.
A Engenharia de tráfego MPLS deve ser habilitada nas interfaces em que os PWs P2MP passam.mpls traffic-eng
interface gigabit <>
auto-tunnel p2mp
tunnel-id min 100 max 200
Enable multicast-routing for interfaces.
multicast-routing
address-family ipv4
interface all enable - A configuração L2VPN para LSM no Cisco IOS XR Release 5.1.0 requer que você:
- Configurar a ID de VPN para o VFI
- Configure o P2MP multicast para o VFI. Configure o protocolo de transporte e o protocolo de sinalização, como neste exemplo de configuração:
l2vpn
bridge group bg
bridge-domain bd1
vfi vf1
vpn-id 1
autodiscovery bgp
rd auto
route-target 209.165.201.7:1
signaling-protocol bgp
ve-id 1
multicast p2mp
signaling-protocol bgp
transport rsvp-te - A LSM Head/Tail deve ser ajustada corretamente. No Cisco IOS XR Release 5.1.0, cada extremidade de LSM também é um Cabeçalho de LSM e vice-versa. Como não há intercâmbio de capacidade LSM explícito entre os roteadores, todos os roteadores em um domínio de bridge habilitado para LSM devem participar do LSM.
Comandos Show e Troubleshooting de L2VPN e L2FIB
- O processo do gerenciador L2VPN (l2vpn_mgr) comunica-se com o processo de controle de Engenharia de Tráfego (TE) de MPLS (te_control) e solicita a criação do túnel. Certifique-se de que os processos te_control e l2vpn_mgr estejam no estado de execução com estes comandos:
- show process l2vpn_mgr
- show process te_control
- verifique se o processo l2vpn_mgr solicitou a criação do túnel. Uma entrada para o túnel deve estar neste comando show:
RP/0/RSP0/CPU0:PE1#show l2vpn atom-db preferred-path
Tunnel BW Tot/Avail/Resv Peer ID VC ID

209.165.200.227 1
209.165.200.228 1 - O L2VPN precisa receber as informações de túnel do processo te_control. Verifique se este comando show tem detalhes diferentes de zero, como tunnel-id, Ext.tunnel-id, tunnel-ifh e p2mp-id:
RP/0/RSP0/CPU0:PE1#show l2vpn atom-db preferred-path private
Tunnel tunnel-mte1 0/0/0:

Ext.tunnel-id: 209.165.200.225 - O L2VPN deve anunciar a PMSI (Provider Multicast Service Instance) a todos os outros roteadores PE. Verifique se l2vpn_mgr enviou o PMSI para o VFI configurado. O evento LSM Head: send PMSI deve estar presente no histórico de eventos do VFI.
