Risoluzione dei problemi relativi al profilo mVPN 14
Sommario
Introduzione
In questo documento viene descritto come risolvere i problemi relativi al profilo Multicast VPN (mVPN) 14 in Cisco IOS® XR.
Prerequisiti
È necessario conoscere il profilo Multicast 14 e il suo comportamento.
Requisiti
Cisco consiglia di configurare il rilevamento automatico di MVPN BGP.
È inoltre consigliabile conoscere i seguenti argomenti:
- Profili - 14
- Albero core - mLDP
- Servizio - VPN IPv4
- Segnalazione C-Overlay - BGP
- Auto-Discovery - BGP
- Modello - Partizione MDT P2MP con BGP AD
- Incapsulamento/inoltro - MPLS
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.
Concetti su mLDP
Albero core - mLDP
- LDP multipunto = LDP + estensioni
- Struttura P2MP - Guidata dal ricevitore - Radice appresa dal routing
- MP2MP tree -Configuration driven -Root configure
- Protezione tramite MPLS TE o LFA (Loop-Free Alternate)
- Nessuna etichetta PHP - Top identifica la struttura
- Replica di mcast sui router principali
- Gli elementi FEC mantengono: tipo di albero + radice + valore opaco: (S, G), numero MDT, ID LSP
mLDP
LSP MP2MP e LSP P2MP
Esistono due modi per inviare il traffico tra i PE.
1. MP2MP: viene creato un MDT statico predefinito tra tutti i PE per un determinato utente. Funziona come se tutti i PE per quell'utente fossero connessi nello stesso segmento LAN.
2. P2MP - quando viene raggiunto un valore di soglia configurabile, il PE mittente può creare un nuovo LSP in modo che solo i PE coinvolti nella comunicazione vedano il traffico, questo LSP viene creato per evitare sprechi inutili di larghezza di banda nell'invio del traffico ai PE che non si sono uniti al flusso. Questo LSP crea solo per una voce (S, G) nella rete di utenti. Se si invia traffico che supera la soglia configurata tramite una voce (*, G), non viene creato alcun nuovo P2MP (il concetto di PHP non può essere utilizzato in questo scenario quando la foglia funge da radice, altrimenti non sa a quale utente appartiene quel traffico).
mLDP funziona con un concetto come root, è in qualche modo simile a un Rendezvous Point nello scenario PIM-SM, ma ricordate, in mLDP, viene menzionato un core MPLS senza PIM, e PIM è abilitato solo nelle interfacce rivolte all'utente.
Nell'albero MP2MP, le radici sono responsabili di ricevere il traffico da una foglia e replicarlo a tutti i vicini direttamente connessi.
Ogni PE può avere più di una radice configurata, scelgono la sua radice attiva in base alla metrica, se la metrica è la stessa l'indirizzo IP più alto viene scelto come radice per quel particolare PE.
Nella struttura P2MP, la radice è sempre il dispositivo che invia il traffico (in questo documento il termine radice è usato più per fare riferimento alla struttura MP2MP, a meno che non sia specificato).
P2MP e MP2MP
Inoltro ricorsivo
Per inoltro ricorsivo si intendono i programmi del control plane mLDP solo (ID downstream, etichetta Outgoing) per il piano di inoltro. L'ID downstream è in genere l'ID del router LDP del nodo downstream. Il piano di inoltro risolve in modo ricorsivo la raggiungibilità al dispositivo a valle e calcola l'effettiva interfaccia in uscita e l'nexthop. L'inoltro ricorsivo abilita funzioni quali il bilanciamento del carico ECMP/LAG, LFA, protezione RSVP-TE e così via. Sfortunatamente, non tutte le piattaforme lo supportano.
Con l'inoltro non ricorsivo, mLDP determina l'interfaccia in uscita e NH al router a valle e ai programmi in modo esplicito (Intf, NH, Etichetta in uscita) nel piano di inoltro.
Configurazione
Questa è la configurazione richiesta per mLDP:
mpls ldp
log
hello-adjacency
neighbor
nsr
graceful-restart
!
igp sync delay on-session-up 25
mldp
address-family ipv4
make-before-break delay 60 60
forwarding recursive
recursive-fec
Questo concetto viene spiegato nella sezione Risoluzione dei problemi. Questa configurazione è richiesta nei router MID e BUD.
Head/Root = Al router è collegata un'origine multicast
Tail/Leaf = Questo router ha ricevitori multicast
Bud = Questo router è in transito e ha alcuni ricevitori collegati
Mid = Questo router è in transito
Label Switch Multicast (LSM)/NG mVPN
- Incapsulamento MPLS > Condivisione del controllo e del piano dati con unicast
- Utilizzo dei nuovi protocolli dell'albero di base > mLDP, P2MP TE, BIER
- Fast ReRoute (FRR)
- Utilizzo di funzionalità comprovate: MDT predefinito e dati
- Design più flessibili per VPN
- Gestibilità: non è necessario tenere traccia dei gruppi multicast per VPN/Default/Data MDT
BGP
AF IPv4 mVPN
AF IPv4 mVPN è stato aggiunto per supportare i profili NG. È nota come MCAST-VPN NLRI.
Questa famiglia di indirizzi ha due funzioni principali:
- Rilevamento automatico (AD)
- Segnalazione cliente in sovrimpressione
L'individuazione automatica significa che i router PE vengono a conoscenza reciprocamente in modo automatico. I router PE apprendono quali altri router PE sono abilitati per il multicast per una VPN. In questo modo si evita la necessità di configurare manualmente questa funzionalità su ogni router PE.
La segnalazione utente in sovrimpressione è la segnalazione di informazioni (*, G) o (S, G), ma ora è in BGP anziché in PIM.
Nella Figura A è illustrata la panoramica della VPN IPv4 di BGP AD.
Figura A - BGP IPv4 AD MVPN
Ci sono due importanti informazioni realizzate da BGP nella VPN IPv4 AF. La prima parte delle informazioni si trova nell'NLRI stesso. Un numero compreso tra 1 e 7 rappresenta il tipo di route. Ogni tipo di route dispone di una funzione specifica. I primi 5 vengono utilizzati per BGP-AD. Il tipo di route 3 viene in realtà utilizzato anche per la segnalazione Data MDT (S-PMSI).
Gli ultimi due tipi, 6 e 7, vengono utilizzati per la segnalazione multicast C. Accanto al Tipo di route sono incluse informazioni specifiche sul tipo di route relative al Desktop remoto (se viene utilizzato il contesto VPN), informazioni specifiche sul multicast C (origine, gruppo) e l'indirizzo IP (PE) del mittente.
La seconda parte è rappresentata dall'attributo del tunnel PMSI (PTA). Questo PTA contiene informazioni relative ai tunnel dell'albero principale utilizzati. Il tipo di tunnel indica il numero del protocollo dell'albero di base utilizzato per compilare il tunnel. L'identificatore del tunnel è un set di campi che descrive in modo univoco il tunnel in base a campi specifici del protocollo della struttura ad albero principale.

MDT partizionato - mLDP P2MP - BGP-AD - Segnalazione C-Mcast BGP - SSM
Topologia Multicast Profile 14
Piattaforma: ASR9K
Procedure per la risoluzione dei problemi
1. Verificare se sono presenti allarmi a livello di sistema sul nodo segnalato (PE/Receiver PE/MID Router di origine).
Show pfm location all
Show logging (Check for critical or major logs)
admin show alarm
2. Verificare la connettività di base MPLS tra il router headend e il router terminale.
3. Verificare la connettività locale dell'origine/ricevitore multicast ai router PE connessi.
4. Controllare la connettività end-to-end tra l'origine multicast e il destinatario.
5. Controllare la configurazione come indicato nella guida alla configurazione menzionata in precedenza.
6. Verifica di base dal controllo dello stato del sistema:
- Controllare se è presente un allarme di sistema (
show pfm location all) - Controllare memoria e CPU
show memory summary location all
show shmwin summary location all
show processes memory detail location all
show process cpu location <> - Controllo dello stato dell'interfaccia e di QoS
- Selezionare show logging, se sono presenti notifiche o errori critici
- Verificare se sono state apportate modifiche alla configurazione dovute a un impatto o a un problema
- Cadute della piattaforma
Il sistema elimina i comandi di verifica
