Command Manual – Multicast

H3C S7500E Series Ethernet Switches

acl-number: 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.

Use the crp-policy command to configure a legal C-RP address range and the range

of served multicast groups, so as to guard against C-RP spoofing.

Use the undo crp-policy command to remove the restrictions in C-RP address ranges

and the ranges of served multicast groups.

By default, there are no restrictions on C-RP address ranges and the address ranges of

served groups, namely all received C-RP messages are accepted.

# Configure a C-RP address range and a range of served multicast groups so that only

routers in the address range of 1.1.1.1/32 can be C-RPs and these C-RPs can serve

only multicast groups in the address range of 225.1.0.0/16.
