• Expires—Time available for the neighbor to send a hello message to the interface.
If the neighbor does not send a hello message during this time, it no longer is a
neighbor.
• Ver—Version of PIM that the neighbor is running
• Mode—PIM mode that the neighbor is using: Sparse, Dense, or SparseDense
• BFD—BFD status: up or down
• Example
host1#show ip pim neighbor
Neighbor
Addr Interface Name Uptime Expires Ver Mode BFD
-------- --------------- -------- -------- --- ------ ---
1.1.1.1 FastEthernet1/1 00:02:49 00:01:27 2 Sparse
Neighbor
Addr Interface Name Uptime Expires Ver Mode BFD
-------- --------------- -------- -------- --- ------ ---
1.1.1.1 FastEthernet1/1 00:03:16 00:01:30 2 Sparse up
Neighbor

• See show ip pim neighbor.
show ip pim rp
• Use to display information about PIM group-to-RP mappings.
• Specify the address of a group to view PIM group-to-RP mappings for a particular
group.
• Specify the mapping keyword to display all group-to-RP mappings that the router has
recorded.
• Field descriptions
• Group(s)—Prefix of the multicast group
• RP—IP address of RP router for the multicast group
• priority—Priority of the router
• via—Method by which the RP router was assigned: AutoRP, Static RP, or BSR
• expiryTime—Time in seconds at which the RP mapping becomes invalid, unless the
mapping agent (access list) reassigns the RP router to this group
• Example 1
host1:8#show ip pim rp mapping
PIM Group-to-RP mapping(s)
Group(s) 224.0.0.0/4
RP 122.0.0.1, priority 0, via AutoRP, expiryTime 88
Group(s) 224.0.1.39/32 (negative)
