VPLS标签交换的组播(LSM)概述

VPLS模拟在多协议标签交换(MPLS)核心间的LAN服务。点到点(P2P) pseudowires全网状(PWs)设置在参加VPLS域为了提供VPLS仿真的所有服务商边缘路由器之间。广播,组播和未知单播流量在对所有观点扫描器的一个VPLS域被充斥。入口复制用于为了发送在每P2P PWs的该泛洪流量到是同一个VPLS域的一部分的所有远程PE路由器。

入口复制缺点

  • 因为同一数据包也许在每P2P的PW,同一条链路多次发送入口复制是效率低的带宽。
  • 当有大量广播和组播VPLS流量时,入口复制能导致重大的被浪费的链路带宽。
  • 因为入口PE路由器负复制的全双工重荷,入口复制也资源加强。

VPLS LSM功能

VPLS是也使用组播传输的一个广泛部署的服务提供商L2VPN技术。虽然L2技术允许将使用的监听为了优化组播数据流的复制到L2 pseudowires,核心依然是不可知论对组播数据流。结果,同一个流的多个副本穿程核心网络。为了缓和此无效用,与VPLS的对LSM为了介绍在核心的LSM组播树。在Cisco IOS XR软件版本5.1.0中, 9000系列的Cisco ASR实现VPLS LSM用点对多点流量工程(P2MP-TE)包括树。VPLS端点自动地发现,并且P2MP-TE树设置使用资源预留协议流量工程(RSVP-TE),不用可操作的干预。

  • VPLS LSM解决入口复制缺点。

  • VPLS LSM解决方案使用在MPLS核心的P2MP LSP为了运载广播,组播和VPLS域的未知单播流量。

  • P2MP LSP允许在MPLS网络至多最佳的节点的复制并且最小化相当数量在网络的信息包复制。

  • VPLS LSM解决方案只发送在P2MP LSP的被充斥的VPLS流量。

  • 单播VPLS流量在P2P PWs仍然发送。在访问发送的流量PWs继续用入口复制传送。

  • P2MP PWs是单向的与P2P PWs相对,双向。

  • VPLS LSM解决方案介入一P2MP PW的创建每个VPLS域为了模拟核心的PWs一VPLS P2MP服务在VPLS域。

  • Cisco IOS XR版本5.1.0支持VPLS LSM及以后。

VPLS LSM限制

  • Cisco IOS XR版本5.1.0 VPLS LSM功能支持仅MPLS流量工程P2MP-TE树设置RSVP-TE。

  • P2MP PW可以发信号与BGP仅协议在Cisco IOS XR版本5.1.0。在此第一阶段,参加VPLS域的远程观点扫描器是自动发现的与BGP自动发现(BGP-AD)。

  • Cisco IOS XR版本5.1.0不支持静态LDP信令。

媒体访问控制(MAC)学习

在分支PE的MAC学习在P2MP PW到达的帧的执行,好象帧在导致该P2MP的PW根PE的P2P PW接收。在此镜像,在PE-2的MAC学习在根源的P2MP PW LSP到达在PE-1的帧的执行,好象帧在PE-1和PE-2之间的P2P PW到达了。L2VPN控制飞机对编程与P2P PW信息的VPLS处理信息负责在P2MP LSP处理的MAC学习的。

互联网组管理协议监听的(IGMPSN)支持

两个支持互联网组管理协议(IGMP)窥探(IGMPSN) P2MP P树的头和尾在参加VPLS LSM的网桥域的。这允许在一个虚拟转发实例(VFI) PWs的IGMPSN组播数据流受益于P2MP LSP提供的资源优化。如果IGMPSN在与一个或更多VFI参加VPLS LSM的PWs的一个网桥域启用,所有第2层(L2)组播数据流在P2MP P树题头发送关联与网桥域。L2组播路由用于为了转发流量到本地接收机,以太网流点(EFPs),不参加VPLS LSM的访问PWs和VFI PWs。

当IGMPSN在是P2MP LSP尾标的网桥域时启用,在P2MP LSP接收的L2组播数据流的优化处理为本地接收机完成(即附件电路(AC)网桥端口(位/秒)和访问PW位/秒)。

注意:Cisco IOS XR版本5.1.0不支持监听组播的标签转发协议(MLDP)。

支持的缩放

Cisco IOS XR版本5.1.0支持最多1000个P2MP通道或1000 P2MP每人的PWs/尾标路由器。

拓扑示例和配置

P2MP通道是自动发现的通道。不支持静态P2MP通道。

没有使用静态隧道配置。如果作为芽节点,必须启用自动P2MP隧道配置在所有PE路由器并且在P路由器。芽节点同时是中央点和尾端路由器。

与配置的一拓扑示例显示此处。在此拓扑方面, P2MP PWs创建在三观点扫描器和作为芽节点的P路由器之间。所有三个PE路由器作为题头(入口流量)和尾标(出口流量)。

排除故障VPLS LSM

常见配置问题

P2MP问题的多数常见原因在L2VPN显示此处。

  • LSM的BGP配置正确地是相同的象那为BGP-AD。确保通过配置BGP邻居的address-family l2vpn VPLsvpws导出/导入l2vpn VPLsvpws地址家族路由。

  • 有MPLS并且组播配置错误。

    在P2MP PWs通过的接口必须启用MPLS流量工程。

    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


  • LSM的L2VPN配置在Cisco IOS XR版本5.1.0要求您:

    • 配置VFI的VPN ID配置
    • 配置VFI的组播P2MP。Confgure传输协议和信令协议,正如在此配置示例:
    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


  • 必须适当地设置LSM题头/尾标。在Cisco IOS XR版本5.1.0中,每LSM尾标也是LSM题头和反过来也是一样地。由于没有在路由器中的明确LSM功能交换, LSM启用的网桥域的所有路由器必须参与LSM。

L2VPN和L2FIB显示命令并且排除故障

  • L2VPN管理器进程(l2vpn_mgr)连通与MPLS流量工程(TE)控制进程(te_control)并且请求隧道创建。保证te_control和l2vpn_mgr进程在运行状态用这些命令:
    • show process l2vpn_mgr
    • show process te_control


  • 检查l2vpn_mgr进程请求隧道创建。通道的一个条目应该在此show命令:

    RP/0/RSP0/CPU0:PE1#show l2vpn atom-db preferred-path
    Tunnel               BW Tot/Avail/Resv    Peer ID            VC ID
    ----------------------------------------------------------------------
    tunnel-mte1 0/0/0                         209.165.200.226    1
                                                         209.165.200.227    1
                                                         209.165.200.228    1


  • L2VPN必须获得从te_control进程的隧道信息。验证此show命令有非零详细信息例如隧道ID、Ext.tunnel id、通道ifh和p2mp-id :

    RP/0/RSP0/CPU0:PE1#show l2vpn atom-db preferred-path private
    Tunnel tunnel-mte1 0/0/0:
      Peer ID: 209.165.200.226, VC-ID 1

  • 每个路由器是LSM头和尾,并且应该发送PMSI和接收从其他路由器中的每一的PMSIs。被检查的第一个路由器应该接收从其他节点中的每一的PMSIs。

  • 第2层转发信息库(L2FIB)必须获得从L2VPN的顶头信息,并且必须下载他们到线路卡。
