Syntax: show ip pim nbr
This display shows the following information.
Displaying information about an upstream
neighbor device
You can view information about the upstream neighbor device for a given source IP address for IP
PIM and DVMRP packets. For PIM, the software uses the IP route table or multicast route table to
lookup the upstream neighbor device. For DVMRP, the software uses the DVMRP route table to
locate the upstream neighbor device.
Enter the following command at the Privileged EXEC level of the CLI.
BigIron RX# show ip pim rpf 1.1.20.2
directly connected or via an L2 neighbor
NOTE
If there are multiple equal cost paths to the source, the show ip pim rpf command output may not
be accurate. If your system has multiple equal cost paths, use the command show ip pim mcache
to view information about the upstream neighbor.
The following example outputs show other messages that the BigIron RX displays with this
command.
This field... Displays...
Port The interface through which the BigIron RX is connected to the neighbor.
Neighbor The IP interface of the PIM neighbor interface.
Holdtime sec Indicates how many seconds the neighbor wants this BigIron RX to hold
the entry for this neighbor in memory. The neighbor sends the Hold Time
in its Hello packets.
•
If the BigIron RX receives a new Hello packet before the Hold Time
received in the previous packet expires, the BigIron RX updates its
table entry for the neighbor.
•
If the BigIron RX does not receive a new Hello packet from the
neighbor before the Hold time expires, the BigIron RX assumes the
neighbor is no longer available and removes the entry for the
neighbor.
Age sec The number of seconds since the BigIron RX received the last hello
message from the neighbor.
UpTime sec The number of seconds the PIM neighbor has been up. This timer starts
when the BigIron RX receives the first Hello messages from the neighbor.
