JNCIP-SP: Juniper Networks Certified Professional – Service Provider (2021) — Question 29

You are asked to configure PIM-SM in your network. Your implementation must allow for load sharing between redundant RPs and, should an RP failure occur, the RP failover time should be minimized.
Which two configuration tasks are required in this scenario? (Choose two.)

Answer options

• A. Configure MSDP peering sessions between the routers designated as RPs.
• B. Configure the shared anycast address on the RPs as the primary address on the loopback interface.
• C. On the routers designated as RPs, configure the shared anycast address on the loopback interface.
• D. Configure at least two static RPs and bundle them in an RP redundancy group under [edit protocols pim].

Correct answer: B, D

Explanation

The correct answer is B and D because configuring the shared anycast address on the loopback interface (B) allows for a single address to be used by multiple RPs, facilitating quick failover. Additionally, having at least two static RPs in an RP redundancy group (D) enables load sharing and helps minimize failover time in case of an RP failure. Options A and C do not specifically address the requirements for redundancy and failover time.
