PIM BSR RP (Non-Local)

To determine which routing device is the RP, all routing devices within a Protocol Independent Multicast (PIM) domain collect bootstrap messages. A PIM domain is a contiguous set of routing devices that implement PIM. All the devices are configured to operate within a common boundary. The domain's bootstrap router initiates bootstrap messages, which are sent hop by hop within the domain. The routing devices use bootstrap messages to distribute RP information dynamically and to elect a bootstrap router when necessary.
