Command Manual – Multicast
H3C S7500E Series Ethernet Switches Chapter 4 PIM Configuration Commands
4-12
Parameters
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.
Description
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.
Examples
# 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.
