    Monitoring Join Interface Details When IPv6 OIF Mapping Is Configured

    Purpose

    Display details of the join interfaces corresponding to the mapped interfaces when OIF mapping is configured.

    • 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 details of the join interfaces:

    host1#show ipv6 mroute oif-detail
                      IPv6 Multicast Routing Table
    (S, G) uptime d h:m:s[, expires d h:m:s]
    [Data rate: Kbps] [SPT threshold: Kbps] 
    [Threshold: Kbps]
      [Admission bandwidth: bps]
      [QoS bandwidth: bps]
      RPF route: addr/mask, incoming interface
                 neighbor address, owner route-owner
      Incoming interface list:
          Interface (addr/mask), State/Owner [(RPF IIF)]
      Outgoing interface list:
          Interface (addr/mask), State/Owner, Uptime/Expires
      Join interface list:
    		Interface (addr/mask)[, State/Owner]
     (2000::1, ff1e::1) uptime 0 00:00:04
      Admission bandwidth: 60000000 bps
      QoS bandwidth: 0 bps (adaptive)
      RPF route: 2000::1/128, incoming interface GigabitEthernet13/1/1
                 neighbor 2000::1, owner Local
      Incoming interface list:
          GigabitEthernet13/1/1 (fe80::290:1aff:fe42:8e5a/128), Accept/Mld (RPF IIF)
      Outgoing interface list:
          GigabitEthernet13/1/4 (fe80::290:1aff:fe42:8e5d/128), Blocked (intf-adm-limit)/Mld, 0 00:00:04/never
    					Join interface list:
    						GigabitEthernet15/0/1.10 (fe80::290:1aff:fe42:2731/128)
    Counts: 1 (S, G) entries
            0 (*, G) entries

    Meaning

    Table 1 lists the show ipv6 mroute oif-detail command output fields.

    Join interface list

    List of join interfaces on the router. Details include:

    • Type of interface and its specifier
