4000 Router Series IP Multicast Command Reference

In an ACL, the source field specifies the legal C-RP address range, and the destination field specifies the

multicast group range to which the C-RP is designated. If you specify a VPN instance in the ACL, the ACL

does not take effect. The other optional parameters except the time-range keyword and the fragment

keyword are ignored.

The crp-policy command filters the multicast group ranges advertised by C-RPs based on the group

prefixes. For example, if the multicast group range that a C-RP advertises is 224.1.0.0/16 but the

multicast group range that the crp-policy command defines is 224.1.0.0/30, the multicast group range

224.1.0.0/16 can pass.

Examples

# On the public network, configure the legal C-RP address range to 1.1.1.1/24 and the multicast group

ra n g e t o 225.1.1.0 / 24 , s o t h a t o n l y d e v i c e s i n t h e a d d re s s ra n g e o f 1.1.1.1 / 24 c a n b e C - R Ps fo r t h e

multicast group range 225.1.1.0/24.
