Configuring C-RPs

About C-RP configuration

To guard against C-RP spoofing, configure a C-RP policy to filter C-RP advertisement messages by using an ACL that specifies the packet source address range and IPv6 multicast groups.

Restrictions and guidelines

Configure C-RPs on devices that reside in the backbone network.

Because the RP and other devices exchange a large amount of information in the BIDIR-PIM domain, reserve a large bandwidth between C-RPs and other devices.

You must configure the same C-RP policy on all C-BSRs in the BIDIR-PIM domain because every C-BSR might become the BSR.
