Monitoring Multicast Routes When OIF Mapping Is Configured

Purpose

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

Action

To display details of the join interfaces:

host1#show ip mroute oif-detail
                  IP Multicast Routing Table
(S, G) uptime d h:m:s[, expires d h:m:s]
  [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
 (10.0.1.9, 225.1.1.1) uptime 0 00:00:23
  Admission bandwidth: 1998724 bps (adaptive)
  QoS bandwidth: 1998724 bps (adaptive)
  RPF route: 10.0.0.0/8, incoming interface ATM2/1.200
             neighbor 21.1.1.1, owner Netmgmt
  Incoming interface list:
      ATM2/1.200 (21.2.2.2/8), Accept/Pim (RPF IIF)
  Outgoing interface list:
      ATM2/1.300 (31.2.2.2/8), Forward/IGMP, 0 00:00:23/never
				Join interface list:
						ATM2/1.2 (2.2.2.2/32), Blocked (intf-adm-limit)/IGMP, 0 00:00:23/never
						ATM2/1.3 (3.2.2.2/32), Forward/IGMP, 0 00:00:23/never
Counts: 1 (S, G) entries
        0 (*, G) entries

Meaning

Table 9 lists the show ip mroute oif-detail command output fields.

Table 9: show ip mroute oif-detail Output Fields

Field Name

Field Description

(S,G)

IP 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

IP address and subnetwork mask of the RPF route

Incoming interface

Type and specifier of the incoming interface for the RPF route

neighbor address

IP 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 such as RIP or OSPF

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

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-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

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
