Usage guidelines This command guards against C-RP spoofing. 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 fragment keyword and the time-range 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 # Configure the legal C-RP address range to 1.1.1.1/24 and the multicast group range to 225.1.1.0/24, so that only devices in the address range of 1.1.1.1/24 can be C-RPs for the multicast group range 225.1.1.0/24. system-view [Sysname] acl number 3000 [Sysname-acl-adv-3000] rule permit ip source 1.1.1.1 0.0.0.255 destination 225.1.1.0 0.0.0.255 [Sysname-acl-adv-3000] quit [Sysname] pim [Sysname-pim] crp-policy 3000 Related commands c-rp (PIM view) display pim bsr-info Use display pim bsr-info to display BSR information in the PIM-SM domain.
