Override Bootstrap Router Updates
PIM-SM routers need to know the address of the RP for each group for which they have (*,G) entry. This
address is obtained automatically through the bootstrap router (BSR) mechanism or a static RP
configuration.
If you have configured a static RP for a group, use the option override with the command [ip | ipv6] pim
rp-address to override bootstrap router updates with your static RP configuration. If you do not use this
option, the RPs advertised in the BSR updates take precedence over any statically configured RPs.
Display the assigned RP for a group using the command
show [ip | ipv6] pim rp from EXEC privilege
mode, as shown in the example below.
FTOS#show ip pim rp
Group RP
225.0.1.40 165.87.50.5
226.1.1.1 165.87.50.5
Display the assigned RP for a group range (group-to-RP mapping) using the command show ip pim rp
mapping command in EXEC privilege mode
FTOS#show ip pim rp mapping
