Which Multicast Protocols Do AR Series Routers Support?

In versions earlier than V200R005C00, the AR series routers support the following multicast protocols:

  • Multicast Source Discovery Protocol (MSDP)

  • Protocol independent multicast sparse mode (PIM-SM)

  • Protocol independent multicast dense mode (PIM-DM)

  • Internet Group Management Protocol (IGMP)

  • IGMP Snooping and MLD Snooping

    NOTE:

    AR150&AR200 series routers and AR1200 series routers do not support IGMP Snooping and MLD Snooping.

    In versions earlier than V200R003C01, the AR200-S series routers and AR1200-S series routers do not support IGMP Snooping and MLD Snooping.

    In V200R003C01 and later versions, AR120-S&AR150-S&AR200-S series routers and AR1200-S series routers do not support IGMP Snooping and MLD Snooping.

In V200R005C00 and later versions, the AR series routers support the following multicast protocols:

  • Multicast Source Discovery Protocol (MSDP)

  • Protocol independent multicast sparse mode (PIM-SM)

  • Protocol independent multicast sparse mode (PIM-SM) for IPv6

  • Protocol independent multicast dense mode (PIM-DM)

  • Protocol independent multicast dense mode (PIM-DM) for IPv6

  • Internet Group Management Protocol (IGMP)

  • Multicast Listener Discovery (MLD)

  • IGMP Snooping and MLD Snooping

    NOTE:

    AR120 series and AR120-S series do not support PIM, MSDP, PIM(IPv6) and MLD.

    Only AR129CV, AR129CVW, AR129CGVW-L, AR2200&AR3200&AR3600 series and AR2200-S&AR3200-S series support IGMP Snooping.
