What is a characteristic of the PIM Candidate BSR?

The PIM Candidate BSR (Bootstrap Router) plays a critical role in the PIM-SM (Protocol Independent Multicast Sparse Mode) protocol operation by facilitating the election of a Rendezvous Point (RP). One of its primary functions is to collect RP information from various RPs within the multicast domain and then disseminate that information to routers within the PIM network.

This characteristic is essential because it enables routers to learn about available RPs, facilitating efficient multicast group management. By distributing information about RPs, the BSR simplifies the process of multicast routing and ensures that multicast traffic can be efficiently directed to the intended receivers.

In contrast, the other options pertain to different functions or responsibilities that do not accurately describe the role of the Candidate BSR. For instance, forwarding join messages directly to the RP is not a responsibility of the Candidate BSR, as its purpose is not to relay join messages, but rather to manage and distribute RP information. Similarly, while listening to auto-RP announcements is a function of routers participating in the auto-RP mechanism, it does not define the role of the Candidate BSR, which specifically pertains to RP information collection and dissemination. Lastly, the statement regarding it always being the highest IP address router does not apply
