JNCIP-DC: Juniper Networks Certified Professional – Data Center (2024) — Question 25

You are asked to build redundant gateways in your EVPN-VXLAN environment, but you must conserve address space because these gateways must span across seven PEs.
What should you implement on the PEs to satisfy these requirements?

Answer options

• A. Use IRB interfaces with the same IP and MAC address.
• B. Use IRB interfaces with the same IP address and different MAC addresses.
• C. Use IRB interfaces with different IP addresses and the same VGA.
• D. Use IRB interfaces with the same IP and VGA.

Correct answer: B

Explanation

The correct answer is B because using the same IP address with different MAC addresses allows multiple gateways to be recognized without consuming additional IP addresses, which is crucial for conserving address space. Option A is incorrect as identical IP and MAC addresses would cause conflicts. Option C does not satisfy the requirement for redundancy with a shared IP, and option D fails to provide the necessary distinction in MAC addresses.
