Displaying PIM Data and Configuration Settings
Syntax: show ip pim [neighbor]
Lists PIM neighbor information for all PIM neighbors
connected to the routing switch:
IP Address: Lists the IP address of a neighbor multicast router.
VLAN: Lists the VLAN through which the routing switch
connects to the indicated neighbor.
Up Time: Shows the elapsed time during which the neighbor
has maintained a PIM route to the routing switch.
Expire Time: Indicates how long before the routing switch ages-
out the current flow (group membership). This value decre­
ments 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
.
If the IP-ADDR is specified then detailed information for the
specified neighbor is shown.
This example simulates output from Routing Switch “#1” in Figure 3-4 on Page
3-20. The data identifies the first downstream neighbor (“Routing Switch #2”).
