QuestionQ116
Multicast Routing
Refer to the exhibit. Routers R1, R2, R3, and R4 are peer routers in separate administrative domains. PIM-SM runs in every autonomous system, and EBGP is configured between the peers. A network administrator has just implemented MSDP between the directly connected peers. After the MSDP configuration was enabled, R1 and R2 did not establish a peering relationship. All other connected routers successfully formed peering sessions. What action must the engineer take to resolve the issue between R1 and R2?
- A Implement BGP authentication between the peers.
- B Configure the peers to be in the same autonomous system.
- C Change the MSDP authentication method to clear text.
- D Set the same MSDP password on both peers.
