# 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 19 lists the show ipv6 mroute oif-detail command output fields.

Table 19: show ipv6 mroute oif-detail Output Fields

Field Name | Field Description
--- | ---
(S,G) | IPv6 addresses of the multicast source and the multicast group
Uptime | Length of time that the (S,G) pair has been active, in days hours:minutes:seconds format
Expires | Length of time for which the (S,G) pair will be active, in days hours:minutes:seconds format
Admission bandwidth | Admission bandwidth (in bps)
QoS bandwidth | QoS bandwidth (in bps)
RPF Route | IPv6 address and prefix of the RPF route
Incoming interface | Type and specifier of the incoming interface for the RPF route
neighbor address | IPv6 address of the neighbor
owner | Owner of the route: Local—route belonging to the local interface Static—Static route Other protocols—Route established by a protocol
Incoming interface list | List of incoming interfaces on the router. Details include: Type of interface and its specifier Action that the interface takes with packets: accept or discard Multicast protocol that owns the interface Time that the interface has been active in this multicast forwarding entry, in days hours:minutes:seconds format Time that the interface will cease to be active in this multicast forwarding entry, in days hours:minutes:seconds format
Outgoing interface list | List of outgoing interfaces on the router. Details include: Type of interface and its specifier Action that the interface takes with packets: Forward or Blocked (intf-adm-limit, join-intf-adm-limit, port-adm-limit, port-limit, port-priority-limit) Protocol running on the interface: PIM or MLD Time that the interface has been active in this multicast forwarding entry, in days hours:minutes:seconds format Time that the interface will cease to be active in this multicast forwarding entry, in days hours:minutes:seconds format
Join interface list | List of join interfaces on the router. Details include: Type of interface and its specifier Action that the interface takes with packets: Forward or Blocked (intf-adm-limit, join-intf-adm-limit, port-adm-limit, port-limit, port-priority-adm-limit) Protocol running on the interface: PIM, DVMRP, or IGMP Amount of time that the interface has been active in this multicast forwarding entry, in days hours:minutes:seconds format Length of time that the interface can remain active in this multicast forwarding entry, in days hours:minutes:seconds format or never
Counts | Numbers of types of source group mappings: (S,G)—Number of (S,G) entries (*,G)—Number of (*,G) entries
