Displaying PIM neighbor data

These commands enable listings of either all PIM neighbors the router detects or the data for a

specific PIM neighbor.

Syntax:

show ip pim neighbor

Lists PIM neighbor information for all PIM neighbors connected to the router:

IP Address Lists the IP address of a neighbor multicast router.

VLAN Lists the VLAN through which the router connects to the indicated

neighbor.

Up Time Shows the elapsed time during which the neighbor has

maintained a PIM route to the router.

Expire Time Indicates how long before the router ages-out the current flow

(group membership.) This value decrements until:

• Reset by a state-refresh packet originating from the upstream

multicast router. (The upstream multicast router issues

state-refresh packets for the current group as long as it either

continues to receive traffic for the current flow or receives

state-refresh packets for the current flow from another

upstream multicast router.

• Reset by a new flow for the current multicast group on the

VLAN.

• The timer expires (reaches 0.) In this case, the switch has

not received either a state-refresh packet or new traffic for

the current multicast group and ages-out (drops) the group

entry.

DR Priority Shows the currently configured priority for DR operation on the

interface.
