Configuring a C-RP
In a BIDIR-PIM domain, you can configure routers that intend to become the RP as C-RPs. The BSR collects
the C-RP information by receiving the C-RP-Adv messages from C-RPs or auto-RP announcements from
other routers and organizes the information into an RP-set, which is flooded throughout the entire network.
Then, the other routers in the network calculate the mappings between specific group ranges and the
corresponding RPs based on the RP-set. H3C recommends that you configure C-RPs on backbone routers.
To guard against C-RP spoofing, configure a legal C-RP address range and the range of multicast groups
to which the C-RP is designated on the BSR. In addition, because every C-BSR has a chance to become
the BSR, you must configure the same filtering policy on all C-BSRs in the BIDIR-PIM domain.
When you configure a C-RP, ensure a relatively large bandwidth between this C-RP and the other devices
in the BIDIR-PIM domain.

Enabling auto-RP
Auto-RP announcement and discovery messages are addressed to the multicast group addresses
224.0.1.39 and 224.0.1.40. With auto-RP enabled on a device, the device can receive these two types
of messages and record the RP information carried in such messages.
