Configuring an RP
An RP can be manually configured or dynamically elected through the BSR mechanism. For a large PIM
network, static RP configuration is a tedious job. Generally, static RP configuration is just a backup
method for the dynamic RP election mechanism to enhance the robustness and operational
manageability of a multicast network.
IMPORTANT:
In a PIM network, if both PIM-SM and BIDIR-PIM are enabled, do not configure the same RP to provide
services for PIM-SM and BIDIR-PIM simultaneously to avoid PIM routing table errors.
Configuring a static RP
If only one dynamic RP exists in a network, manually configuring a static RP can avoid communication
interruption because of single-point failures. It can also avoid frequent message exchange between C-RPs
and the BSR.
To enable a static RP to work normally, perform this configuration on all the routers in the PIM-SM domain
and specify the same RP address.
To configure a static RP:
