PIM - BSR

PIM BSR (Bootstrap Routing) - the basics

The BSR mechanism is a nonproprietary method of defining RPs that can be used with third-party routers. There is no configuration necessary on every router separately (except on candidate-BSRs and candidate-RPs). The canidate-RPs are analagous with Auto-RP candidate RPs and the candidate-BSRs are analagous with the Auto RP mapping agent.

Thes can be defined as follows.

R1
ip pim rp-candidate Loopback0

R3
ip pim rp-candidate Loopback0

R5
ip pim bsr-candidate Loopback0 31
