R3303-HP HSR6800 Routers IP Multicast Command Reference

118
Parameters
acl-number: Specifies an advanced ACL number in the range of 3000 to 3999. When the ACL is defined,
the source keyword in the rule command specifies the address of a C-RP and the destination keyword
specifies the address range of the multicast groups that the C-RP will serve.
Usage guidelines
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 and the legal
group range that the crp-policy command defines is 224.1.0.0/30, the multicast groups in the range of
224.1.0.0/16 can pass.
Examples
# On the public network, configure a legal C-RP policy so that only devices in the address range of
1.1.1.1/24 can be C-RPs that serve multicast groups in the address range of 225.1.1.0/24.
