Caso aziendale: Multicast L3 in ACI Fabric
Introduzione
Il routing multicast di layer 3 è supportato nel fabric ACI a partire dalla versione 2.0 e richiede switch EX (ad esempio N9K-C93180YC-EX). Prima della release 2.0, ACI supportava solo multicast L2 all'interno del dominio bridge. Questa opzione è ancora valida nella versione 2.0 e può essere utilizzata per switch non EX.
In ACI release 2.0, le funzioni di routing multicast supportate includono: PIM ASM, PIM SSM, Static RP, PIM Auto-RP e PIM BSR.
In questo documento viene descritta una soluzione convalidata per uno scenario di implementazione reale del cliente per il routing multicast L3 su fabric ACI. La versione ACI selezionata è 2.1(1h). Questa release non supporta RP nella struttura, pertanto è necessario un RP esterno per PIM ASM.
Requisiti di progettazione
Il cliente richiede una soluzione end-to-end per il routing multicast L3 all'interno e all'esterno del fabric. Lo scenario di distribuzione presenta i requisiti seguenti:
- Un VRF distribuito per tutti i tenant.
Nota: Il multicast richiede un'uscita L3 dedicata per ciascun VRF. Se nell'infrastruttura sono presenti più VRF, l'uscita L3 condivisa non è supportata per il routing multicast.
- Ricevitori in fabric con fonti esterne
- Fonti in fabric con ricevitori esterni
- Fonti e ricevitori nel fabric
- RP statica o Auto-RP
Soluzione
Revisione topologia
Nella topologia sono presenti due componenti principali: il modulo ACI e il modulo Tiered LAN Network. Entrambi i moduli sono collegati ai dispositivi principali tramite collegamenti L3 point-to-point con OSPF e PIM. Nel modulo ACI, la rete con routing esterno è chiamata L3out-to-Core associata al VRF common:default. Include i quattro collegamenti dalle due foglie di bordo ai dispositivi principali. Il modulo di rete LAN su più livelli, definito esterno al fabric, è costituito dal tradizionale layer di accesso e di aggregazione con vPC.
I flussi multicast L3 vengono eseguiti attraverso la struttura ACI e la rete LAN legacy attraverso il layer Core. Per lo scenario RP statico, RP viene distribuito sul dispositivo edge WAN.
Utilizziamo generatori di traffico a spirale (STC) per simulare le fonti e i ricevitori interni ed esterni. Le porte Spirent sono collegate a diverse posizioni nel modulo ACI e nel modulo di rete LAN su più livelli. I riceventi inviano messaggi di partecipazione a IGMP v2.
Origini interne collegate a Sleaf2: gli IP di origine sono 10.101.101.115~124, inviando a indirizzi di gruppo: 228.0.0.1~10
Ricevitori interni collegati a Bleaf1, Cleaf1 e Cleaf2: I BD con supporto multicast sono BD90, BD91, BD31, BD32 e gruppi interessati: 228.0.0.1~10 e 229.0.0.1~10.
Origini esterne collegate al livello di accesso nella rete LAN: gli IP di origine sono 10.103.103.40~49, inviando a indirizzi di gruppo: 229.0.0.1~10.
Ricevitori esterni collegati al livello di accesso nella rete LAN: vlan131, vlan132, gruppi interessati: 228.0.0.1~10.
Configurazione
Passaggio 0: Impostare RP sul dispositivo WAN simulato collegato al core, abilitare la modalità sparse PIM sui dispositivi di rete LAN a livelli.
!!!!! RP configuration ip pim rp-address 99.99.99.99 group-list 224.0.0.0/4 ip pim ssm range 232.0.0.0/8 interface loopback99 ip address 99.99.99.99/32 ip router ospf 65017 area 0.0.0.0 ip pim sparse-mode interface Ethernet2/1 ip pim sparse-mode interface Ethernet2/2 ip pim sparse-mode
Passaggio 1: Abilitare il multicast sul VRF. In Spazio tenant, selezionare Rete > VRF > Multicast, nel pannello di lavoro, fare clic sul burro per abilitare il multicast.
Passaggio 2: abilitare il multicast ai livelli di uscita BD e L3e abilitare IGMP per i BD ricevitori. Selezionare Rete > VRF > Nome VRF > Multicast, nel pannello di lavoro selezionare Configurazione > scheda Interfaccia, fare clic su "+" per aggiungere i domini bridge in cui è previsto il traffico multicast. Abilitare i criteri IMGP per BD con supporto multicast.
Quindi fare clic su "+" per aggiungere L3out per questo VRF. Quando il multicast è abilitato per un L3out, il PIM verrà abilitato su tutte le interfacce sotto l3out e tutti i bordi lasciati per tale L3out verranno abilitati con il routing multicast. Selezionare il criterio PIM per i gruppi di interfacce L3out.
Si supponga che i BD e l3out siano già dotati di provisioning.
L'associazione dei criteri IGMP ai BD lo rende anch'esso un query IGMP. I criteri IGMP sono configurati in Tenant > Reti > Criteri protocollo > Interfaccia IGMP. Il criterio IGMP predefinito prevede i parametri seguenti, in cui è possibile definire gli intervalli di query. Se non viene specificato alcun criterio, l'interfaccia utilizzerà il criterio predefinito.
La policy PIM è configurata anche in Tenant > Reti > Protocol Policies > PIM.
Il criterio PIM predefinito prevede i parametri seguenti, in cui è possibile definire gli intervalli di saluto.
È necessario configurare L3Outs su foglia bordo con indirizzi di loopback abilitati nel profilo del nodo.
Passaggio 3: Configurare RP per PIM ASM. Passare a Tenant > VRF > Multicast, nel pannello di lavoro selezionare Configurazione > Punti di rendering. Nell'esempio, è selezionato RP statico. Fare clic su "+" per aggiungere l'RP.
Per la configurazione Auto-RP, selezionare le caselle "Inoltra aggiornamenti Auto-RP" e "Ascolta aggiornamenti Auto-RP" nella pagina "Rendezvous Points".
Al di fuori della struttura ACI, le configurazioni AUTO-RP sulle piattaforme NX-OS rimangono le stesse.
!!! On RP candidate ip pim send-rp-announce loopback99 group-list 224.0.0.0/4 ip pim send-rp-discovery loopback99 scope 32 !!! On RP listeners: ip pim auto-rp listen forward
Passaggio 4: configurare le impostazioni PIM necessarie. Passare a Tenant >VRF -> Multicast, nel pannello di lavoro, selezionare Configuration > PIM settings (Configurazione > Impostazioni PIM), notare l'indirizzo VRF GIPo 225.1.192.0/32 assegnato da APIC dal pool di indirizzi del gruppo multicast. Il GIPo VRF verrà utilizzato come indirizzo IP del gruppo esterno per il traffico multicast per i BD abilitati con PIM.
Quando la modalità Fast Convergence è abilitata (l'impostazione predefinita è disabilitata), tutte le foglie dei bordi abilitate con PIM invieranno join alla rete esterna, ma solo una foglia dei bordi inoltrerà il traffico sulla struttura per evitare duplicati. La foglia di bordo che inoltra il traffico per il gruppo è il mittente designato per il gruppo. L'abilitazione della funzionalità Fast Convergence consente di ridurre la durata di rilascio dei pacchetti per i flussi multicast con origini esterne e ricevitori interni, in caso sia presente una modifica del vincitore dello stripe dovuta al fatto che il bordo foglia è inattivo. Non si verifica alcuna latenza quando si unisce l'albero PIM del nuovo vincitore dello stripe. Questo avviene al costo dell'uso aggiuntivo della larghezza di banda sui collegamenti esterni dei vincitori non-stripe, dal momento che tutte le foglie di confine estraggono il traffico dalla fonte esterna.
Informazioni sui vincitori di striping - Attualmente ACI utilizza un hash BSR (Bootstrap Router) per calcolare il vincitore di striping BL. L'hash viene calcolato utilizzando l'indirizzo IP di loopback S,G e Leaf. A partire da ACI 3.0(1) non c'è modo di influenzare la scelta del vincitore della striscia per l'utente.
Passaggio 5: Creare il contratto necessario per consentire il traffico multicast:
- Origine e ricevitore all'interno del fabric (contratto non necessario)
- Ricevitore all'interno del fabric, fonte esterna (contratto non necessario)
- Origine all'interno del fabric, ricevitore esterno (contratto obbligatorio)*
*Il contratto non è richiesto se il BD è installato sulla foglia del bordo
Nel nostro caso, abbiamo ricevitori al di fuori del fabric, applicare il contratto tra L3out_to_Core e mcast source in EPG101.
Verifica
Verifica PIM
Quando il VRF è abilitato per il routing multicast, viene creata un'interfaccia di infrastruttura (tunnel) per il routing multicast all'interno dell'infrastruttura. I pacchetti del control plane PIM vengono inviati tramite le interfacce di infrastruttura all'interno dell'infrastruttura. La destinazione del tunnel sarà l'indirizzo multicast GiPo VRF. Sugli switch border leaf, l'origine del tunnel sarà l'interfaccia di loopback sul border leaf. Sugli switch foglia non frontalieri l'origine del tunnel sarà un indirizzo di loopback (127.0.0.100).
Il bordo lascia inviare hellop PIM sull'interfaccia del fabric.Le interfacce L3Out eseguono PIM in modalità normale, tra cui l'invio e la ricezione di hellop, la selezione di DR, ecc. Le foglie non-border funzionano in modalità passiva sull'interfaccia del fabric; ascoltano i pim hellos dalle foglie di confine ma non li inviano. Le foglie esterne non verranno visualizzate nell'output per "show ip pim neighbors".

Verifica attiva foglia bordo
Se con routing multicast sono abilitate più foglie di bordo, APIC sceglie un vincitore di striping per ogni indirizzo di gruppo su tutte le foglie di bordo attive. La foglia di confine vincitrice dello stripe per un gruppo è responsabile dell'invio di join PIM per conto del fabric e dell'inoltro del traffico multicast nel fabric.
Il vincitore della striscia per il gruppo decide sul mittente designato. Se il vincitore della striscia è raggiungibile dalla radice, il vincitore della striscia è anche il DF. Se il vincitore dello stripe non dispone di connettività esterna alla radice, BL sceglie un DF inviando un join PIM sull'interfaccia fabric.

Sui router principali, N7K-core-1 e N7K-core-2 condividono il carico per i flussi multicast provenienti dalla rete LAN. Se la convergenza veloce non è abilitata, solo una foglia di bordo (bleaf1) sta inviando il join verso l'origine.
