Componenti usati
Il documento può essere consultato per tutte le versioni software o hardware.
Le informazioni discusse in questo documento fanno riferimento a dispositivi usati in uno specifico ambiente di emulazione. Su tutti i dispositivi menzionati nel documento la configurazione è stata ripristinata ai valori predefiniti. Se la rete è operativa, valutare attentamente eventuali conseguenze derivanti dall'uso dei comandi.
Panoramica di VPLS Label Switched Multicast (LSM)
VPLS emula i servizi LAN su un core Multiprotocol Label Switching (MPLS). Tra tutti i router Provider Edge (PE) che partecipano a un dominio VPLS viene configurata una rete completa di pseudofili (PW) point-to-point (P2P) per fornire l'emulazione VPLS. Il traffico broadcast, multicast e unicast sconosciuto viene inondato in un dominio VPLS a tutti i PE. La replica in ingresso viene utilizzata per inviare il traffico di flooded su ogni PW P2P a tutti i router PE remoti che fanno parte dello stesso dominio VPLS.
Svantaggi della replica in ingresso
- La replica in ingresso non è efficiente a livello di larghezza di banda, in quanto lo stesso pacchetto potrebbe essere inviato più volte sullo stesso collegamento per ogni PW P2P.
- La replica in ingresso può comportare uno spreco significativo della larghezza di banda del collegamento in caso di traffico broadcast e multicast VPLS elevato.
- Anche la replica in ingresso richiede un uso intensivo delle risorse, in quanto il router PE in entrata sopporta l'intero carico della replica.
Funzioni VPLS LSM
VPLS è una tecnologia L2VPN ampiamente implementata dal provider di servizi che viene utilizzata anche per il trasporto multicast. Sebbene la tecnologia L2 consenta l'utilizzo dello snooping per ottimizzare la replica del traffico multicast negli alimentatori L2, il core rimane indipendente dal traffico multicast. Di conseguenza, più copie dello stesso flusso attraversano le reti principali. Per ridurre questa inefficienza, abbinare LSM a VPLS in modo da introdurre gli alberi multicast LSM nel core. Nel software Cisco IOS-XR versione 5.1.0, Cisco ASR serie 9000 implementa VPLS LSM con alberi inclusivi di progettazione del traffico point-to-multipoint (P2MP-TE). Gli endpoint VPLS vengono rilevati automaticamente e gli alberi P2MP-TE vengono impostati con l'utilizzo di Resource Reservation Protocol Traffic Engineering (RSVP-TE) senza alcun intervento operativo.
- VPLS LSM consente di superare gli inconvenienti della replica in entrata.
- La soluzione LSM VPLS impiega LSP P2MP nel core MPLS per trasportare il traffico broadcast, multicast e unicast sconosciuto per un dominio VPLS.
- I provider di servizi di traduzione P2MP consentono la replica nella rete MPLS al nodo ottimale e riducono al minimo la quantità di replica dei pacchetti nella rete.
- La soluzione VPLS LSM invia solo il traffico VPLS in modalità flooded sugli LSP P2MP.
- Il traffico VPLS unicast viene ancora inviato sui PW P2P. Il traffico inviato tramite i PW di accesso continua a essere inviato con la replica in entrata.
- I PW P2MP sono unidirezionali rispetto ai PW P2P, che sono bidirezionali.
- La soluzione VPLS LSM implica la creazione di una PW P2MP per dominio VPLS al fine di emulare un servizio P2MP VPLS per i PW di base nel dominio VPLS.
- VPLS LSM è supportato in Cisco IOS XR versione 5.1.0 e successive.
Restrizioni VPLS LSM
- Cisco IOS-XR release 5.1.0 VPLS LSM supporta solo alberi P2MP-TE di progettazione del traffico MPLS configurati con RSVP-TE.
- Una PW P2MP può essere segnalata con il protocollo BGP solo in Cisco IOS-XR release 5.1.0. In questa prima fase, i PE remoti che partecipano al dominio VPLS vengono rilevati automaticamente con BGP Auto-Discovery (BGP-AD).
- La segnalazione LDP statica non è supportata in Cisco IOS XR versione 5.1.0.
Apprendimento MAC (Media Access Control)
L'apprendimento MAC sul PW foglia per un frame che arriva sul PW P2MP viene eseguito come se il frame fosse ricevuto sul PW P2P che porta al PW radice per quel PW P2MP. In questa immagine, MAC Learning su PE-2 per i frame che arrivano su P2MP PW LSP con radice in PE-1 viene eseguito come se il frame arrivasse su P2P PW tra PE-1 e PE-2. Il control plane L2VPN è responsabile della programmazione delle informazioni di disposizione VPLS con informazioni PW P2P per l'apprendimento MAC sulla disposizione LSP P2MP.
Supporto IGMPSN (Internet Group Management Protocol Snooping)
Lo snooping IGMP (Internet Group Management Protocol) (IGMPSN) è supportato sia sulla parte iniziale che finale dell'albero P2MP in un dominio bridge che partecipa a VPLS LSM. In questo modo, il traffico multicast IGMPSN su PW di un'istanza di inoltro virtuale (VFI) può trarre vantaggio dall'ottimizzazione delle risorse fornita dai PSP P2MP. Se IGMPSN è abilitato in un dominio bridge con una o più PW VFI che partecipano a VPLS LSM, tutto il traffico multicast di livello due (L2) viene inviato sulla testa P2MP dell'albero associato al dominio bridge. Le route multicast L2 vengono utilizzate per inoltrare il traffico ai ricevitori locali, ai punti di flusso Ethernet (EFP), ai PW di accesso e ai PW VFI che non partecipano al modulo LSM VPLS.
Quando IGMPSN è abilitato in un dominio bridge che è una coda LSP P2MP, la disposizione ottimizzata del traffico multicast L2 ricevuto sull'LSP P2MP viene effettuata per i ricevitori locali (cioè, porte Bridge (BP) del circuito di collegamento (AC) e accesso ai BP del PW).
Scala supportata
Cisco IOS XR release 5.1.0 supporta un massimo di 1000 tunnel P2MP o 1000 PW P2MP per router head/tail.

Topologia e configurazione di esempio
I tunnel P2MP sono tunnel rilevati automaticamente. I tunnel P2MP statici non sono supportati.
Non vengono utilizzate configurazioni di tunnel statici. La configurazione automatica del tunnel P2MP deve essere abilitata su tutti i router PE e anche su un router IP se funge da nodo bud. Un nodo build è un router intermedio e allo stesso tempo un router terminale.
Di seguito è riportato un esempio di topologia con configurazione. In questa topologia, i PW P2MP vengono creati tra i tre PE e un router IP che funge da nodo bud. I tre router PE fungono da testa (per il traffico in entrata) e coda (per il traffico in uscita).

Risoluzione dei problemi di VPLS LSM
Problemi comuni di configurazione
Di seguito sono indicate le cause più comuni dei problemi P2MP in L2VPN.
- La configurazione BGP per LSM è esattamente la stessa di BGP-AD. Accertarsi di esportare/importare le route della famiglia di indirizzi l2vpn vpls-vpws configurando le route della famiglia di indirizzi l2vpn vpls-vpws per i router adiacenti BGP.
- Errori di configurazione MPLS e multicast.
MPLS Traffic Engineering deve essere abilitato sulle interfacce su cui passano i PW P2MP.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 configurazione L2VPN per LSM in Cisco IOS XR release 5.1.0 richiede quanto segue:
- Configurare la configurazione dell'ID VPN per la VFI
- Configurare il protocollo IP2MP multicast per la VFI. Configurare il protocollo di trasporto e il protocollo di segnalazione, come nell'esempio seguente:
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 testa/coda dell'LSM deve essere impostata correttamente. In Cisco IOS XR release 5.1.0, ogni coda LSM è anche una testa LSM e viceversa. Poiché non vi è scambio esplicito di funzionalità LSM tra i router, tutti i router di un dominio bridge abilitato a LSM devono partecipare a LSM.
Comandi L2VPN e L2FIB Show e risoluzione dei problemi
- Il processo di gestione L2VPN (l2vpn_mgr) comunica con il processo di controllo MPLS Traffic Engineering (TE) (te_control) e richiede la creazione del tunnel. Verificare che i processi te_control e l2vpn_mgr siano in esecuzione con i seguenti comandi:
- show process l2vpn_mgr
- show process te_control
- Verificare che il processo l2vpn_mgr abbia richiesto la creazione del tunnel. Una voce per il tunnel deve essere in questo comando show:

209.165.200.227 1
209.165.200.228 1 - L2VPN deve ricevere le informazioni sul tunnel dal processo te_control. Verificare che il comando show abbia dettagli diversi da zero, ad esempio 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 - L2VPN deve annunciare l'istanza del servizio multicast del provider (PMSI) a tutti gli altri router PE. Verificare che l2vpn_mgr abbia inviato il PMSI per la VFI configurata. L'intestazione LSM dell'evento: invio PMSI deve essere presente nella cronologia degli eventi per la VFI.
