9.3.5.3Filters for Register Message from RP

One network may include different multicast groups and routers that are not members of multicast group. Therefore it can happen that routers, which are members of another network or not members of multicast group, apply for RP and transmit candidate-RP message.

To prevent this case, user can block candidate-RP message of another router by making only candidate-RP in multicast group communicate. In order to block candidate-RP mes- sage from routers which are not members, perform the below tasks.

Step 1

Configure filtering out multicast sources.

Command	Mode	Description
ip pim accept-register list {<100-		Configures multicast source filtering function.
		100-199: IP extended access-list
199> <2000-2699> ACCESS-	Global
		2000-2699: IP extended access list (expanded range)
LIST}
		ACCESS-LIST: IP named Standard Access List

Step 2

Allow or deny only the transmitted packets by routers that exchange candidate-RP mes- sage.

Command	Mode	Description
access-list{<100-199> <2000-		Configures multicast source filtering function.
		100-199: IP extended access list
2699>} {deny permit} ip	Global
		2000-2699: IP extended access list (expanded range)
{A.B.C.D any}
		A.B.C.D: address to match

To delete the above configuration, use the following command.

Command	Mode	Description
no ip pim accept-register	Global	Releases blocked packet.
