PIM Configuration Commands
6-4
Description
Use the c-rp command to configure the router to advertise itself as a candidate RP to
the BSR.
Use the undo c-rp command to remove the configuration.
By default, no candidate RP is configured, and the value of RP priority is 0.
During candidate RP configuration, a relatively large bandwidth should be reserved for
the router and other devices in the PIM domain.
Related commands: c-bsr.
Examples
# Configure the switch to advertise to the BSR that the switch itself is the C-RP in the
PIM domain. Basic ACL 2000 defines the range of groups related to the RP. The
address of C-RP is designated as the IP address of VLAN-interface10.
