    Monitoring Summary Information of IPv6 Multicast Routes

    Purpose

    Display a summary of all or specified multicast routes.

    • You can specify a multicast group address or both a multicast group address and a multicast source address to display information about a particular multicast forwarding entry.
    • You can use the active option to display information for the active multicast routes.
    • You can specify the bandwidth threshold along with the active option to display information for the active multicast routes with admission bandwidth greater than the specified bandwidth threshold. The default bandwidth threshold is 4000 bps.

    Action

    To display a summary of all multicast routes:
