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:
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.
