PIM Interface Table

The PIM Interface Table contains an entry for each of the router PIM ports. The PIM Interface Table lists the IPM multicast group members on specific ports.

The PIM Interface Table displays the following fields:

• IfIndex — Specifies the PIM port number.

• Interface Address — Indicates the PIM port IP address.

• Interface Mask — Masks all or part of PIM port IP addresses.

• Designated Router — Identifies the designated router on each multi-access router. The designator router polls the LAN to determine group membership. The router with the highest IP address is the designated router. If the designated router times out, a new designated router is elected from the alternate PIM routers. Designated routers are used for multi-access networks. Point-to-point links display the value 0.0.0.0.

• Hello Interval — Indicates in seconds the amount of time ports send hello messages. PIM-DM routers keep track of neighboring interfaces based on received hello messages. Neighbor information is deleted if there it is not refreshed before expiration. The default time is 30 seconds.

• JointPrune Intervals — Indicates the intervals at which Join/Prune messages are sent to the PIM router. The PIM router assumes that all downstream routers can receive multicast packets, flooding the network with multicast packets. If specific network areas do not have multicast group members, PIM-DM prunes off the forwarding branch by establishing a Prune state. The Prune state contains the source and multicast group address, and contains a timer. When the timer expires the network branch goes into a forwarding state. The default is 210 seconds.
