Clearing Multicast Route Entries from PIM Routing Table
Perform the following configuration in User View.

from PIM routing
[ mask {
table
incoming-interface {
null } } } * }
If in this command, the
the RP address (where group address can have a mask, but the resulted 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
is 0 (where group address can have a mask, and source address
source-address
has no mask), then only the (*, G) item will be cleared.
