Configuring the Router's IPv4 Bootstrap Router Priority

To determine which router is the RP, all routers within a PIM domain collect bootstrap messages. A PIM domain is a contiguous set of routers that implement PIM; all are configured to operate within a common boundary. The domain's bootstrap router originates bootstrap messages, which are sent hop by hop within the domain. The routers use bootstrap messages to distribute RP information dynamically and to elect a bootstrap router when necessary.

By default, the router has a bootstrap priority of 0, which means the router can never be the bootstrap router. To modify this priority, include the bootstrap-priority statement. The router with the highest priority value is elected to be the bootstrap router. In the case of a tie, the router with the highest IP address is elected to be the bootstrap router. A simple bootstrap configuration simply assigns a bootstrap priority value to a router.
