Table 326: show pim interfaces Output Fields
(continued)
Field Description
Field Name
PIM mode running on the interface:
•
Sparse
—In sparse mode, routing devices must join and leave multicast groups explicitly. Upstream
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
—Unlike sparse mode, where data is forwarded only to routing devices sending an explicit
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-dense mode allows the interface to operate on a per-group basis in either
sparse or dense mode. A group specified as
dense
is not mapped to a rendezvous point (RP).
Instead, data packets destined for that group are forwarded using PIM-Dense Mode (PIM-DM)
rules. A group specified as
sparse
is mapped to an RP, and data packets are forwarded using
PIM-Sparse Mode (PIM-SM) rules.
Mode
Version number of the address family on the interface:
4
(IPv4) or
6
(IPv6).
IP
PIM version running on the interface:
1
or
2
.
V
State of PIM on the interface:
•
DR
—Designated router.
•
NotDR
—Not the designated router.
•
P2P
—Point to point.
State
Number of neighbors that have been seen on the interface.
NbrCnt
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)
Address of the designated router.
