D - Dense = group works in dense mode
S - Sparse - group works in sparse mode
C - Connected = there is a directly connected receiver
L - Local = the router itself is a receiver
P - Pruned = a PRUNE was sent upstream (no neighbors or receivers downstream)
T - Shortest Path Tree = the group uses a SPT.
PIM-SM - Only on (S,G) entries
PIM-SM - (*,G) signals a SPT switchover. The next packet will be routed using the (S,G). Recalculate threshod once a second
- (S,G) signals a SPT switchover. Recalculates threshold once a minute.
F - REGISTER = there's a source on this interface
R - information in the (S,G) applies to the shared tree
