An animal control HQ must choose how multi-site county routers learn which router is the RP for camera groups. Which comparison correctly describes static RP, Auto-RP, and BSR?
Select an answer to reveal the explanation.
Short Explanation
Static RP is like writing the meeting room on a whiteboard—everyone must see the same note. Auto-RP and BSR are the building PA system that announces “RP for these groups is over here.” Pick static for small, tightly controlled fabrics; pick dynamic mapping when many routers must stay in sync without constant touch.
Full Explanation
Static RP configuration places identical RP addresses (often with ACLs for group ranges) on every PIM router; it is simple and deterministic but error-prone at scale. Auto-RP (Cisco) and Bootstrap Router (BSR, standards-based) distribute RP-to-group mapping information dynamically so routers converge without per-box static edits. Neither Auto-RP nor BSR removes the need for PIM-SM itself; MSDP is a separate mechanism often paired with anycast RP, not a prerequisite for Auto-RP or BSR.
