Explanation

PIM Bidirectional (PIM-BIDIR) is optimized for many-to-many multicast communication patterns, such as trading floors or conferencing applications where multiple sources send to multiple receivers. Unlike PIM-SM which builds separate (S,G) source trees, PIM-BIDIR uses only a shared bidirectional tree rooted at the RP, reducing multicast state. For the RP address, any IP address reachable within the network-including an address configured on any router interface-can serve as the RP. This is sometimes extended with 'phantom RP' (an IP not assigned to any interface) for redundancy, but an interface IP is also valid. PIM-BIDIR does not use explicit (S,G) join messages; traffic flows toward and away from the RP on the shared tree without source-specific state.
