NEW QUESTION # 135
An engineer is designing a PIM Anycast RP solution between two data centers. The design must ensure that RP1 in DC1 and RP2 in DC2 inform each other about specific sources that have joined locally. Which solution must the engineer choose?
- A. Enable MSDP between RPs using the configured Anycast RP address
- B. No action is required because PIM registers from the source will, by default, reach each RP
- C. Provision the RPs on the same IP subnet and extend the subnet at Layer 2 between data centers
- D. Enable MSDP between RPs using separate unique loopback interfaces
Answer: D
Explanation:
In Anycast RP, two or more RPs are configured with the same IP address on loopback interfaces. The Anycast RP loopback address should be configured with a 32-bit mask, making it a host address. All the downstream routers should be configured to "know" that the Anycast RP loopback address is the IP address of their local RP. IP routing automatically will select the topologically closest RP for each source and receiver.
MSDP used for Anycast RP is an intradomain feature that provides redundancy and load-sharing capabilities. Enterprise customers typically use Anycast RP for configuring a Protocol Independent Multicast sparse mode (PIM-SM) network to meet fault tolerance requirements within a single multicast domain.

" You need to have a loopback on each prospective RP router, which is different than the loopback that is being used as the RP address."

- B. totally not so stubby
- C. stubby area
- D. totally stubby area
Answer: D
