7.5.2.10 ip pimsm crppreference
This command is used to configure the Candidate Rendezvous Point (CRP) for a particular
PIM-SM interface. The valid values are from (-1 to 255), and the value of -1 is used to
indicate that the local interface is not a Candidate RP interface.
The active router interface, with the highest IP Address and crppreference greater than -1, is
chosen as the CRP for the router. The default value is 0.
In the CRP advertisements sent to the bootstrap router (BSR), the router interface advertises
itself as the CRP for the group range 224.0.0.0 mask 240.0.0.0.
Syntax
ip pimsm crppreference <-1 - 255>
no ip pimsm crppreference
