ASR 9000 — 瞭解和配置VPLS LSM
目錄
簡介
本檔案介紹執行Cisco IOS® XR軟體的聚合服務路由器(ASR)9000系列的虛擬私人LAN服務(VPLS)標籤交換多點傳送(LSM)。

本文件沒有特定需求。
採用元件
本文件所述內容不限於特定軟體和硬體版本。
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。
VPLS標籤交換多點傳送(LSM)概觀
VPLS模擬跨多協定標籤交換(MPLS)核心的LAN服務。在參與VPLS域的所有提供商邊緣(PE)路由器之間設定全網狀點對點(P2P)偽線(PW)，以便提供VPLS模擬。廣播、組播和未知的單播流量在VPLS域中泛洪到所有PE。入口複製用於將泛洪流量通過每個P2P PW傳送到屬於同一VPLS域所有遠端PE路由器。
入口複製的缺點
- 入口複製頻寬效率低下，因為對於每個P2P PW，同一資料包可能通過同一鏈路傳送多次。
- 當廣播和組播VPLS流量較重時，入口複製可能會導致大量浪費鏈路頻寬。
- 入口複製也會佔用大量資源，因為入口PE路由器承擔了複製的全部負擔。
VPLS LSM功能
VPLS是一種廣泛部署的服務提供商L2VPN技術，也用於組播傳輸。雖然L2技術允許使用窺探來最佳化將多點傳播流量複製到L2偽線，但核心層仍不受多點傳播流量的影響。因此，同一流的多個副本會遍歷核心網路。為了緩解這種低效率，將LSM與VPLS配對，以便在核心上引入LSM組播樹。在Cisco IOS-XR軟體版本5.1.0中，Cisco ASR 9000系列使用包含點對多點流量工程(P2MP-TE)的樹來實作VPLS LSM。通過使用資源預留協定流量工程(RSVP-TE)自動發現VPLS端點並設定P2MP-TE樹，而無需操作干預。
- VPLS LSM克服了入口複製的缺點。
- VPLS LSM解決方案在MPLS核心中使用P2MP LSP來承載VPLS域的廣播、組播和未知的單播流量。
- P2MP LSP允許在最佳節點的MPLS網路中複製，並將網路中的資料包複製量降至最低。
- VPLS LSM解決方案僅通過P2MP LSP傳送泛洪VPLS流量。
- 單播VPLS流量仍通過P2P PW傳送。通過接入PW傳送的流量繼續通過入口複製傳送。
- P2MP PW是單向的，而P2P PW是雙向的。
- VPLS LSM解決方案包括每個VPLS域建立P2MP PW，以便為VPLS域中的核心PW模擬VPLS P2MP服務。
- Cisco IOS XR 5.1.0版及更新版本支援VPLS LSM。
VPLS LSM限制
- Cisco IOS-XR版本5.1.0 VPLS LSM功能僅支援使用RSVP-TE設定的MPLS流量工程P2MP-TE樹。
- P2MP PW只能在Cisco IOS-XR 5.1.0版中使用BGP協定進行發訊號。在第一階段，使用BGP自動發現(BGP-AD)自動發現參與VPLS域的遠端PE。
- Cisco IOS XR 5.1.0版不支援靜態LDP信令。
媒體存取控制(MAC)學習
對於到達P2MP PW的幀，在枝葉PE上進行MAC學習就像在P2P PW上收到該幀，導致該P2MP PW的根PE。在此圖中，對於根位於PE-1的P2MP PW LSP上到達的幀，在PE-2上進行MAC學習，就好像幀在PE-1和PE-2之間的P2P PW上到達一樣。L2VPN控制平面負責使用P2P PW資訊對VPLS配置資訊進行程式設計，以用於P2MP LSP配置上的MAC學習。
網際網路群組管理通訊協定窺探(IGMPSN)支援
參與VPLS LSM的橋接域中P2MP P樹的頭部和尾部都支援網際網路組管理協定(IGMP)監聽(IGMPSN)。這允許通過虛擬轉發例項(VFI)PW的IGMPSN組播流量從P2MP LSP提供的資源最佳化中受益。如果在橋接域中啟用了IGMPSN，並且有一個或多個VFI PW參與VPLS LSM，則所有第二層(L2)組播流量都會通過與該橋接域關聯的P2MP P-tree Head傳送。L2多點傳送路由用於將流量轉送到不參與VPLS LSM的本地接收器、乙太網路流量點(EFP)、存取PW和VFI PW。
當在作為P2MP LSP尾的橋接域中啟用IGMPSN時，對本地接收器(即，連線電路(AC)橋接埠(BP)和接入PW BP)在P2MP LSP上接收到的L2組播流量進行最佳化配置。
支援的擴展
Cisco IOS XR 5.1.0版最多支援每個頭/尾路由器1000 P2MP隧道或1000 P2MP PW。

拓撲和配置示例
P2MP隧道是自動發現的隧道。不支援靜態P2MP通道。
不使用靜態隧道配置。如果自動P2MP隧道配置充當了bud節點，則必須在所有PE路由器以及P路由器上啟用。bud節點同時是中點和尾端路由器。
此處顯示具有配置的示例拓撲。在此拓撲中，P2MP PW在三個PE之間和作為bud節點的P路由器之間建立。所有三台PE路由器都充當Head（用於輸入流量）和Tail（用於輸出流量）。

排除VPLS LSM故障
常見配置問題
此處顯示了L2VPN中P2MP問題的最常見原因。
- LSM的BGP配置與BGP-AD的BGP配置完全相同。通過為BGP鄰居配置address-family l2vpn vpls-vpws，確保匯出/匯入l2vpn vpls-vpws地址系列路由。
- 存在MPLS和組播配置錯誤。
必須在P2MP PW通過的介面上啟用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 - Cisco IOS XR 5.1.0版中LSM的L2VPN配置要求您：
- 配置VFI的VPN ID配置
- 為VFI配置組播P2MP。設定傳輸通訊協定和訊號通訊協定，如以下範例設定所示：
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 - 必須正確設定LSM頭/尾。在Cisco IOS XR 5.1.0版中，每個LSM尾端也是LSM頭，反之亦然。由於路由器之間沒有明確的LSM功能交換，因此啟用LSM的網橋域中的所有路由器都必須參與LSM。
L2VPN和L2FIB Show命令和故障排除
- L2VPN管理器進程(l2vpn_mgr)與MPLS流量工程(TE)控制進程(te_control)通訊並請求建立隧道。使用以下命令確保te_control和l2vpn_mgr進程處於運行狀態：
- show process l2vpn_mgr
- show process te_control
- 檢查l2vpn_mgr進程是否已請求隧道建立。通道的專案應位於此show命令中：
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必須從te_control進程接收隧道資訊。驗證此show命令是否具有非零詳細資訊，例如tunnel-id、Ext.tunnel-id、tunnel-ifh和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 - L2VPN必須向所有其他PE路由器通告提供商組播服務例項(PMSI)。檢查l2vpn_mgr是否已傳送已配置VFI的PMSI。VFI的事件歷史記錄中應包含事件LSM Head:send PMSI。
