PIM-SM (Sparse Mode)
Displaying PIM-SM Data and Configuration Settings
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
Designated Router (DR) operation on the interface.
