614 BigIron RX Series Configuration Guide53-1001986-01Displaying PIM Sparse configuration information and statistics23Syntax: show ip pim nbrThis display shows the following information.Displaying information about an upstream neighbor deviceYou can view information about the upstream neighbor device for a given source IP address for IPPIM and DVMRP packets. For PIM, the software uses the IP route table or multicast route table tolookup the upstream neighbor device. For DVMRP, the software uses the DVMRP route table tolocate the upstream neighbor device.Enter the following command at the Privileged EXEC level of the CLI.BigIron RX# show ip pim rpf 1.1.20.2directly connected or via an L2 neighborNOTEIf there are multiple equal cost paths to the source, the show ip pim rpf command output may notbe accurate. If your system has multiple equal cost paths, use the command show ip pim mcacheto view information about the upstream neighbor.The following example outputs show other messages that the BigIron RX displays with thiscommand.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 holdthe entry for this neighbor in memory. The neighbor sends the Hold Timein its Hello packets.• If the BigIron RX receives a new Hello packet before the Hold Timereceived in the previous packet expires, the BigIron RX updates itstable entry for the neighbor.• If the BigIron RX does not receive a new Hello packet from theneighbor before the Hold time expires, the BigIron RX assumes theneighbor is no longer available and removes the entry for theneighbor.Age sec The number of seconds since the BigIron RX received the last hellomessage from the neighbor.UpTime sec The number of seconds the PIM neighbor has been up. This timer startswhen the BigIron RX receives the first Hello messages from the neighbor.BigIron RX(config-pim-router)# show ip pim nbrPort Neighbor Holdtime Age UpTimesec sec sece3/8 207.95.8.10 180 60 900Port Neighbor Holdtime Age UpTimesec sec secv1 207.95.6.2 180 60 900
