View IP Multicast Information

View IP multicast routes the virtual router uses, IGMP interfaces and settings, and PIM information and settings.
After you Configure IP Multicast routing, view multicast routes, forwarding entries, and information about your IGMP and PIM interfaces.
  • Select
    Network
    Virtual Routers
    and in the row for the virtual router you configured, click

    .
    1. Select
      Routing
      Route Table
      and then the
      Multicast
      radio button to display only multicast routes (destination IP multicast group, the next hop toward that group, and outgoing interface). This information comes from the mRIB.
    2. Select
      Multicast
      FIB
      to view multicast route information from the mFIB: multicast groups to which the virtual router belongs, the corresponding source, incoming interfaces, and outgoing interfaces toward the receivers.

      IGMP
      Interface
      to view IGMP-enabled interfaces, the associated IGMP version, IP address of the IGMP Querier, Querier up time and expiry time, the robustness setting, limits on numbers of multicast groups and sources, and whether the interface is configured for immediate leave.

      PIM
      Group Mapping
      to view multicast groups mapped to an RP, the origin of the RP mapping, the PIM mode for the group (ASM or SSM), and whether the group is inactive. Groups in SSM mode don’t use an RP, so the RP address displayed is 0.0.0.0. The default SSM group is 232.0.0.0/8.
