Enabling PIM-SM
With PIM-SM enabled, a router sends hello messages periodically to discover PIM neighbors and
processes messages from the PIM neighbors. To deploy a PIM-SM domain, enable PIM-SM on all
non-border interfaces of the routers.

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.
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 make a static RP to work correctly, you must perform this configuration on all routers in the PIM-SM
domain and specify the same RP address.
