Field Name Field Description
PIM mode running on the interface:
Mode
Sparse
routing devices do not forward multicast traffic to this routing device unless this device has sent
an explicit request (using a join message) to receive multicast traffic.
Dense
request, dense mode implements a flood-and-prune mechanism, similar to DVMRP (the first
multicast protocol used to support the multicast backbone).
Sparse-Dense
sparse or dense mode. A group specified as
Instead, data packets destined for that group are forwarded using PIM-Dense Mode (PIM-DM)
rules. A group specified as
PIM-Sparse Mode (PIM-SM) rules.
IP Version number of the address family on the interface:
V PIM version running on the interface:
State State of PIM on the interface:

P2P
NbrCnt Number of neighbors that have been seen on the interface.
Number of (s,g) join messages that have been seen on the interface.
JoinCnt(sg)
Number of (*,g) join messages that have been seen on the interface.
JointCnt(*g)
