9.3.5.3 Filters 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-
199> | <2000-2699> | ACCESS-
LIST}
Global
Configures multicast source filtering function.
100-199: IP extended access-list
2000-2699: IP extended access list (expanded range)
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-
2699>} {
deny | permit} ip
{A.B.C.D | any}
Global
Configures multicast source filtering function.
100-199: IP extended access list
2000-2699: IP extended access list (expanded range)
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.
9.3.5.4 Source Address of Register Message

source IP address, use ip pim register-source command. The configured address must
be a reachable address to be used by the RP to send corresponding Register-Stop mes-
