Présentation du protocole LSM (Label Switched Multicast) VPLS
VPLS émule les services LAN sur un coeur MPLS (Multiprotocol Label Switching). Un maillage complet de pseudo-fils (PW) point à point (P2P) est configuré entre tous les routeurs Provider Edge (PE) qui participent à un domaine VPLS afin de fournir l'émulation VPLS. Le trafic de diffusion, de multidiffusion et de monodiffusion inconnue est diffusé dans un domaine VPLS à tous les PE. La réplication d'entrée est utilisée afin d'envoyer ce trafic inondé sur chaque PW P2P à tous les routeurs PE distants qui font partie du même domaine VPLS.
Inconvénients de la réplication entrante
- La réplication en entrée est inefficace en termes de bande passante, car le même paquet peut être envoyé plusieurs fois sur la même liaison pour chaque PC2P.
- La réplication en entrée peut entraîner un gaspillage important de la bande passante de liaison en cas de trafic VPLS de diffusion et de multidiffusion important.
- La réplication en entrée est également gourmande en ressources, car le routeur PE en entrée supporte la charge totale de la réplication.
Fonctionnalités VPLS LSM
VPLS est une technologie L2VPN de fournisseur de services largement déployée qui est également utilisée pour le transport multidiffusion. Bien que la technologie L2 permette d’utiliser la surveillance afin d’optimiser la réplication du trafic de multidiffusion dans les pseudo-fils L2, le coeur reste indépendant du trafic de multidiffusion. Par conséquent, plusieurs copies du même flux traversent les réseaux principaux. Afin d'atténuer cette inefficacité, jumelez LSM avec VPLS afin d'introduire des arbres de multidiffusion LSM sur le coeur. Dans la version 5.1.0 du logiciel Cisco IOS-XR, la gamme Cisco ASR 9000 implémente VPLS LSM avec des arborescences inclues d'ingénierie de trafic point à multipoint (P2MP-TE). Les points d'extrémité VPLS sont automatiquement détectés et les arborescences P2MP-TE sont configurées à l'aide de l'ingénierie de trafic RSVP-TE (Resource Reservation Protocol Traffic Engineering) sans intervention opérationnelle.
- VPLS LSM permet de surmonter les inconvénients de la réplication en entrée.
- La solution VPLS LSM utilise des LSP P2MP dans le coeur MPLS afin de transporter le trafic de diffusion, de multidiffusion et de monodiffusion inconnue pour un domaine VPLS.
- Les LSP P2MP permettent la réplication dans le réseau MPLS au niveau du noeud le plus optimal et minimisent la quantité de réplication de paquets dans le réseau.
- La solution VPLS LSM envoie uniquement le trafic VPLS inondé sur les LSP P2MP.
- Le trafic VPLS de monodiffusion est toujours envoyé sur des PC P2P. Le trafic envoyé sur les PC d'accès continue d'être envoyé avec la réplication d'entrée.
- Les PW P2MP sont unidirectionnels, contrairement aux PW P2P, qui sont bidirectionnels.
- La solution VPLS LSM implique la création d'un PW P2MP par domaine VPLS afin d'émuler un service VPLS P2MP pour les PW principaux dans le domaine VPLS.
- VPLS LSM est pris en charge dans Cisco IOS XR version 5.1.0 et ultérieure.
Restrictions LSM VPLS
- La fonctionnalité LSM VPLS de Cisco IOS-XR version 5.1.0 prend uniquement en charge les arborescences P2MP-TE d'ingénierie de trafic MPLS configurées avec RSVP-TE.
- Un PW P2MP peut être signalé avec le protocole BGP uniquement dans Cisco IOS-XR version 5.1.0. Dans cette première phase, les PE distants qui participent au domaine VPLS sont détectés automatiquement avec la détection automatique BGP (BGP-AD).
- La signalisation LDP statique n'est pas prise en charge dans Cisco IOS XR version 5.1.0.
Apprentissage MAC (Media Access Control)
L'apprentissage MAC sur le PE Leaf pour une trame qui arrive sur le PW P2MP est effectué comme si la trame était reçue sur le PW P2P menant au PE racine pour ce PW P2MP. Dans cette image, l'apprentissage MAC sur PE-2 pour les trames qui arrivent sur le LSP PW P2MP enraciné sur PE-1 est effectué comme si la trame arrivait sur le PW P2P entre PE-1 et PE-2. Le plan de contrôle L2VPN est chargé de programmer les informations de disposition VPLS avec les informations P2P PW pour l'apprentissage MAC sur la disposition P2MP LSP.
Prise en charge de la surveillance IGMPSN (Internet Group Management Protocol)
La surveillance IGMP (Internet Group Management Protocol) (IGMPSN) est prise en charge à la fois sur la tête et la queue de l'arbre P2MP dans un domaine de pont qui participe à VPLS LSM. Cela permet au trafic multidiffusion IGMPSN sur des PW d'instance de transfert virtuelle (VFI) de bénéficier de l'optimisation des ressources fournie par les LSP P2MP. Si IGMPSN est activé dans un domaine de pont avec un ou plusieurs PW VFI participant à VPLS LSM, tout le trafic de multidiffusion de couche 2 (L2) est envoyé sur la tête P2MP P-tree associée au domaine de pont. Les routes de multidiffusion de couche 2 sont utilisées afin de transférer le trafic vers des récepteurs locaux, des points de flux Ethernet (EFP), des PW d'accès et des PW VFI qui ne participent pas à VPLS LSM.
Lorsque l'IGMPSN est activé dans un domaine de pont qui est une queue de LSP P2MP, la disposition optimisée du trafic de multidiffusion de couche 2 reçu sur le LSP P2MP est effectuée pour les récepteurs locaux (c'est-à-dire, les ports de pont (BP) de circuit d'attachement (AC) et les BP d'accès de PW).
Évolutivité prise en charge
Cisco IOS XR version 5.1.0 prend en charge un maximum de 1 000 tunnels P2MP ou 1 000 PW P2MP par routeur tête/queue.

Exemple de topologie et de configuration
Les tunnels P2MP sont des tunnels à détection automatique. Les tunnels P2MP statiques ne sont pas pris en charge.
Les configurations de tunnel statiques ne sont pas utilisées. La configuration automatique du tunnel P2MP doit être activée sur tous les routeurs PE, ainsi que sur un routeur P s'il agit comme un noeud de bourgeon. Un noeud de bourgeonnement est à la fois un routeur milieu et un routeur fin.
Un exemple de topologie avec configuration est présenté ici. Dans cette topologie, les PW P2MP sont créés entre les trois PE et un routeur P qui agit comme un noeud de bourgeon. Les trois routeurs PE agissent en tant que Head (pour le trafic entrant) et Tail (pour le trafic sortant).

Dépannage de VPLS LSM
Problèmes de configuration courants
Les causes les plus courantes des problèmes P2MP dans L2VPN sont présentées ici.
- La configuration BGP pour LSM est exactement la même que celle pour BGP-AD. Assurez-vous d'exporter/importer les routes de la famille d'adresses l2vpn vpls-vpws en configurant address-family l2vpn vpls-vpws pour les voisins BGP.
- Il existe des erreurs de configuration MPLS et multicast.
L'ingénierie de trafic MPLS doit être activée sur les interfaces où les PW P2MP passent.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 - La configuration L2VPN pour LSM dans Cisco IOS XR version 5.1.0 nécessite que vous :
- Configurer la configuration de l'ID VPN pour le VFI
- Configurez la multidiffusion P2MP pour le VFI. Configurez le protocole de transport et le protocole de signalisation, comme dans cet exemple de configuration :
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 - La tête/queue LSM doit être définie correctement. Dans Cisco IOS XR version 5.1.0, chaque queue LSM est également une tête LSM et vice-versa. Comme il n'y a pas d'échange de capacité LSM explicite entre les routeurs, tous les routeurs dans un domaine de pont activé par LSM doivent participer à LSM.
Commandes show L2VPN et L2FIB et dépannage
- Le processus gestionnaire L2VPN (l2vpn_mgr) communique avec le processus de contrôle MPLS Traffic Engineering (TE) (te_control) et demande la création du tunnel. Assurez-vous que les processus te_control et l2vpn_mgr sont à l'état d'exécution avec ces commandes :
- show process l2vpn_mgr
- show process te_control
- Vérifiez que le processus l2vpn_mgr a demandé la création du tunnel. Une entrée pour le tunnel doit être dans cette commande 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 - L2VPN doit recevoir les informations de tunnel du processus te_control. Vérifiez que cette commande show comporte des détails différents de zéro, tels que tunnel-id, Ext.tunnel-id, tunnel-ifh et 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 doit annoncer l'instance PMSI (Provider Multicast Service Instance) à tous les autres routeurs PE. Vérifiez que l2vpn_mgr a envoyé le PMSI pour le VFI configuré. L'événement LSM Head : send PMSI doit être présent dans l'historique des événements pour le VFI.
