El routing multidifusión de capa 3 es compatible con el fabric ACI a partir de la versión 2.0 y requiere switches EX (es decir, N9K-C93180YC-EX). Antes de la versión 2.0, ACI sólo admitía multidifusión L2 dentro del dominio de puente. Esta opción sigue siendo válida en 2.0 y se puede utilizar para switches no EX.
En la versión 2.0 de ACI, las funciones de routing multidifusión admitidas incluyen: PIM ASM, PIM SSM, Static RP, PIM Auto-RP y PIM BSR.
En este documento, describimos una solución validada para un escenario real de implementación del cliente para el ruteo multicast L3 en el fabric ACI. La versión de ACI seleccionada es 2.1(1h). Esta versión no soporta RP en el fabric, por lo que se necesita un RP externo para PIM ASM.
El cliente necesita una solución integral para el ruteo de multidifusión L3 dentro y fuera del fabric. El escenario de implementación tiene los siguientes requisitos:
Nota: La multidifusión requiere L3out dedicado para cada VRF. Si hay varios VRF en el fabric, el L3out compartido no se soporta para el ruteo multicast.
Revisión de topología
En la topología, hay dos componentes principales: el módulo ACI y el módulo Tiered LAN Network. Ambos módulos están conectados a los dispositivos centrales a través de links L3 punto a punto que ejecutan OSPF y PIM. En el módulo ACI, la red enrutada externa se denomina L3out-to-Core asociada con el VRF common:default. Incluye los cuatro enlaces de las dos hojas de borde a los dispositivos principales. El módulo de red LAN por niveles, denominado externo al fabric, consta de la capa de acceso tradicional y la capa de agregación con vPC.
Los flujos de multidifusión L3 se ejecutan en el fabric ACI y la red LAN heredada a través de la capa de núcleo. Para el escenario de RP estático, RP se implementa en el dispositivo de borde WAN.
Utilizamos generadores de tráfico Spirent (STC) para simular las fuentes y receptores internos y externos. Los puertos Spirent están conectados a diferentes ubicaciones en el módulo ACI y el módulo de red LAN por niveles. Los receptores envían mensajes de afiliación de IGMP v2.
Fuentes internas conectadas a la hoja 2: las IP de origen son 10.101.101.115~124, enviando a las direcciones de grupo: 228.0.0.1~10
Receptores internos conectados a Bleaf1, Cleaf1 y Cleaf2: los BD habilitados para multicast son BD90, BD91, BD31, BD32, grupos interesados: 228.0.0.1~10 y 229.0.0.1~10.
Fuentes externas conectadas a la capa de acceso en la red LAN: las IP de origen son 10.103.103.40~49, enviando a las direcciones de grupo: 229.0.0.1~10.
Receptores externos conectados a la capa de acceso en la red LAN: vlan131, vlan132, grupos interesados: 228.0.0.1~10.
Paso 0: Configure RP en el dispositivo WAN simulado conectado al núcleo, habilite el modo disperso de PIM en los dispositivos de red LAN en niveles.
!!!!! 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
Paso 1: Habilitar multidifusión en el VRF. En el espacio del arrendatario, navegue hasta Redes > VRF > Multicast, en el panel de trabajo, haga clic en la mantequilla para habilitar la multidifusión.
Paso 2: Habilite Multicast en los niveles BD y L3out, habilite IGMP para los BD del receptor. Vaya a Networking > VRFs > VRF name > Multicast, en el panel de trabajo, seleccione Configuration > Interface tab, haga clic en "+" para agregar los Bridge Domains donde se espera tráfico multidifusión. Habilite la política IMGP para el BD habilitado multicast.
A continuación, haga clic en "+" para agregar L3out para este VRF. Cuando se habilita multicast para un L3out, habilitará PIM en todas las interfaces bajo L3out, y todos los bordes de ese L3out se habilitan con el ruteo multicast. Seleccione la política PIM para los grupos de interfaces L3out.
Asumamos que los BD y L3out ya están aprovisionados.
La asociación de la política IGMP a los BD también lo convierte en un consultor IGMP. La política IGMP se configura en Arrendatario > Redes > Políticas de protocolo > Interfaz IGMP. La política IGMP predeterminada tiene los siguientes parámetros donde puede definir intervalos de consulta. Si no se especifica ninguna política, la interfaz utilizará la política predeterminada.
La política PIM también se configura en Arrendatario > Redes > Políticas de protocolo > PIM.
La política PIM predeterminada tiene los siguientes parámetros donde puede definir intervalos hello.
Los L3Outs en la hoja de borde se deben configurar con las direcciones de loopback habilitadas en el perfil de nodo.
Paso 3: Configure RP para PIM ASM. Vaya a Arrendatario > VRF > Multicast, en el panel de trabajo seleccione Configuration > Rendezvous Points. En este ejemplo, se selecciona el RP estático. Haga clic en "+" para agregar el RP.
Para la configuración Auto-RP, active las casillas "Reenviar actualizaciones Auto-RP" y "Escuchar actualizaciones Auto-RP" en la página "Puntos de Encuentro".
Fuera del fabric de ACI, las configuraciones AUTO-RP en las plataformas NX-OS siguen siendo las mismas.
!!! 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
Paso 4: Configure los ajustes PIM necesarios. Navegue hasta Arrendatario >VRF -> Multidifusión, en el panel de trabajo, seleccione Configuración > Configuración de PIM, observe la dirección VRF GIPo 225.1.192.0/32 que es asignada por APIC desde el grupo de direcciones de grupo multicast. El VRF GIPo se utilizará como la dirección IP del grupo externo para el tráfico multicast para los BD habilitados con PIM.
Cuando se habilita el modo Convergencia rápida (el valor predeterminado es inhabilitado), todas las hojas de borde habilitadas con PIM enviarán uniones hacia la red externa, pero sólo una hoja de borde reenviará el tráfico al fabric para evitar duplicados. La hoja de borde que reenvía el tráfico para el grupo es el reenviador designado para el grupo. La habilitación de la convergencia rápida ayuda a reducir la duración de la caída de paquetes para los flujos de multidifusión con orígenes externos y receptores internos, cuando hay un cambio de ganador de franjas debido a que la hoja de borde está inactiva. No se produce latencia al unirse al árbol PIM desde el nuevo ganador de la banda. Esto se produce a costa del uso adicional del ancho de banda en los links externos de los ganadores no estriados, ya que todas las hojas de la frontera arrastran el tráfico de la fuente externa.
Acerca de los ganadores de la banda - Actualmente ACI utiliza un hash BSR (Bootstrap Router) para calcular el ganador de la banda BL. El hash se calcula usando la IP de bucle invertido y S,G de la hoja. A partir de ACI 3.0(1) no hay forma de influir en la elección del ganador de la banda para el usuario.
Paso 5: Crear el contrato necesario para permitir el tráfico multidifusión:
- Origen y receptor dentro del fabric (no se necesita contrato)
- Receptor dentro del fabric, fuente externa (no se necesita el contrato)
- Fuente dentro del fabric, receptor externo (se requiere contrato)*
*El contrato no es obligatorio si el BD se implementa en la hoja de frontera
En nuestro caso, tenemos receptores fuera del fabric, aplicamos el contrato entre L3out_to_Core y el origen mcast en EPG101.
Verificación PIM
Cuando se habilita el VRF para el ruteo de multidifusión, se crea una interfaz de fabric (túnel) para el ruteo de multidifusión dentro del fabric. Los paquetes del plano de control PIM se envían a través de las interfaces de fabric dentro del fabric. El destino del túnel será la dirección multicast VRF GiPo. En los switches de hoja de borde, el origen del túnel será la interfaz de loopback en la hoja de borde. En los switches de hoja no fronterizos, el origen del túnel será una dirección de loopback (127.0.0.100).
Las hojas de borde envían hellos PIM en la interfaz de fabric.Las interfaces L3Oout ejecutan PIM en el modo normal incluyendo el envío y recepción de hellos, la selección de DR, etc. Las hojas que no son de borde se ejecutan en modo pasivo en la interfaz de entramado; escuchan los hellos PIM desde la frontera sale pero no envían hellos PIM. Las hojas que no sean de borde no aparecerán en la salida para "show ip pim neighbor".

Verificación de la hoja de borde activa
Si hay más de una hoja de borde habilitada con ruteo multicast, APIC elige una franja ganadora para cada dirección de grupo a través de todas las hojas de borde activas. La hoja de borde que es el ganador de la banda para un grupo es responsable de enviar las uniones PIM en nombre del fabric y reenviar el tráfico multicast al fabric.
El ganador de la banda del grupo decide sobre el Reenvío designado. Si el ganador de la franja tiene disponibilidad para la raíz, entonces el ganador de la franja también es el DF. Si el ganador de la banda no tiene conectividad externa con la raíz, entonces BL elige un DF enviando una unión PIM a través de la interfaz de fabric.
