A university with mixed Cisco and third-party routers needs dynamic rendezvous point election across a new multivendor multicast core, with no manual RP addresses on every router and resilience if the primary candidate fails. Which rendezvous point discovery method supports multivendor dynamic election for this network?
Select an answer to reveal the explanation.
Short Explanation
You're crossing vendor lines and want an election, not manual typing, so standards matter here. BSR gives you dynamic multivendor RP discovery with election, like holding a proper vote instead of appointing someone.
Full Explanation
Bootstrap Router is the standards-based dynamic RP discovery mechanism where candidate RPs advertise and candidate BSRs elect the BSR that floods the RP set hop by hop, so all routers learn the RP without per-router static config and fail over to another candidate. Static RP fails the stated requirement by concept because it demands manual configuration everywhere and provides no native election, increasing operational burden. Auto-RP fails by concept for this multivendor need because it relies on Cisco-proprietary dense-mode flood of Auto-RP announcements and is not guaranteed on third-party platforms. Anycast-RP with MSDP fails because it provides RP redundancy via shared anycast address plus source-active exchange, not dynamic discovery and election of the RP mapping itself. For the exam, associate BSR with PIMv2 standards environments and Auto-RP with Cisco-only legacy; in practice verify BSR peering, RP-set on all routers, and candidate priorities.
