II. Configuring a C-RP
In a PIM-SM 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. We recommend that you configure C-RPs on
backbone routers.
To guard against C-RP spoofing, you need to configure a legal C-RP address range
and the range of multicast groups to be served on the BSR. In addition, because every
C-BSR has a chance to become the BSR, you need to configure the same filtering
policy on all C-BSRs.
