    Router interfaces

    List of information about multicast-router interfaces:

    • Name of the multicast-router interface.
    • static or dynamic—Whether the multicast-router interface has been statically configured or dynamically learned.
    • Uptime—For static interfaces, amount of time since the interface was configured as a multicast-router interface or since the interface last flapped. For dynamic interfaces, amount of time since the first query was received on the interface or since the interface last flapped.
    • timeout—Seconds remaining before a dynamic multicast-router interface times out.

    detail

    Group

    IP multicast address of the multicast group.

    The following information is provided for the multicast group:

    • Name of the interface belonging to the multicast group.
    • Timeout—Time (in seconds) left until a dynamically learned interface is removed from the multicast group if no MLD membership reports are received on the interface. This counter is reset to its maximum value when a membership report is received.
    • Flags—The lowest MLD version in use by a host that is a member of the group on the interface.

      If the flag static is included, the interface has been configured as static member of the multicast group.

    • Receiver count—Number of hosts on the interface that are members of the multicast group. This field appears only if immediate-leave is configured on the VLAN.
    • Last reporter—Last host to report membership for the multicast group.
    • Include source—Multicast source addresses from all MLDv2 membership reports received for the group on the interface.
