If in this command, the group-address is 224.0.0.0/24 and source-address is the
RP address (where group address can have a mask, but the resulting IP address
must be 224.0.0.0, and source address has no mask), then it means only the (*, *,
RP) item will be cleared.
If in this command, the group-address is any group address, and source-address is
0 (where group address can have a mask, and source address has no mask), then
only the (*, G) item will be cleared.
This command clears multicast route entries from PIM routing table, as well as the
corresponding route entries and forward entries in the multicast core routing table
and MFC.
