Why each option
In a multi-vendor PIM-SM environment, the Bootstrap Router (BSR) is the standard feature for dynamically learning the Rendezvous Point (RP).
Auto-RP is a Cisco proprietary solution for dynamic RP discovery and is not compatible with multi-vendor environments.
BIDIR-PIM (Bi-Directional PIM) is a specific PIM mode designed for efficient many-to-many multicast traffic, not a mechanism for dynamic RP discovery.
SSM (Source-Specific Multicast) is a multicast model where receivers explicitly specify the source of traffic, thus eliminating the need for an RP, which is not what the question asks for (dynamic RP learning in PIM-SM).
