Correct Answer: A,D
Explanation:
You can filter Protocol Independent Multicast (PIM) register messages sent from the designated
router (DR) or to the rendezvous point (RP).
Note: In a shared tree, the root of the distribution tree is a router, not a host, and is located
somewhere in the core of the network. In the primary sparse mode multicast routing protocol,
Protocol Independent Multicast sparse mode (PIM SM), the core router at the root of the shared tree
is the rendezvous point (RP).
