The multicast state for the displayed interface.
Interface state
IP multicast group address for a requested service.
group address
Subnetwork containing the IP multicast source.
source
The time elapsed since this entry was created.
uptime
The associated multicast protocol (PIM).
Owner
Interface leading to the upstream neighbor.
Incoming Interface
PIM creates a multicast routing tree based on the unicast routing
table. If the related unicast routing table does not exist, PIM will
still create a multicast routing entry, but displays "Null" for the
upstream interface to indicate that the unicast routing table is not
valid. This field may also display "Register" to indicate that a
pseudo interface is being used to send or receive PIM-SM register
packets.
IP address of the multicast router immediately upstream for this

HAPTER
D (Dense) - PIM Dense mode in use.
S (Sparse) - PIM Sparse mode in use.
s (SSM) - A multicast group with the range of IP addresses
used for PIM-SSM.
C (Connected) - A member of the multicast group is present
on this interface.
P (Pruned) - This route has been terminated.
F (Register flag) - This device is registering for a multicast
source.
R (RP-bit set) - The (S,G) entry is pointing to the
Rendezvous Point (RP), which normally indicates a pruned
state along the shared tree for a particular source.
T (SPT-bit set) - Multicast packets have been received from a
source on the shortest path tree.
J (Join SPT) - The rate of traffic arriving over the shared tree
has exceeded the SPT-threshold for this group. If the SPT
flag is set for (*,G) entries, the next (S,G) packet received
will cause the router to join the shortest path tree. If the SPT
flag is set for (S,G), the router immediately joins the
shortest path tree.
F (Register flag) - This device is registering for a multicast
source.
P (Pruned) - This route has been terminated.
L (Local) - Downstream interface has received IGMP report
message from host in this subnet.
