A . RPF Neighbor
B . RP Set
C . Incoming Interface
D . OIL
E . DF priority
F . PIM SM state flags
Answer: A,C,D,F
Explanation:
The following is sample output from the show ip mroute command for a router operating in sparsemode:

IP Multicast Routing Table
Flags: D – Dense, S – Sparse, C – Connected, L – Local, P – Pruned
R – RP-bit set, F – Register flag, T – SPT-bit set
Timers: Uptime/Expires
Interface state: Interface, Next-Hop, State/Mode
