A city wants active/active Layer-2 stretch across two halls. Which design caution is essential?
Select an answer to reveal the explanation.
Short Explanation
Active/active L2 stretch without careful ESI and gateway design is how you invent loops and duplicate packets. Multihoming detail is not optional.
Full Explanation
Active/active Layer-2 stretch across sites introduces multihoming and gateway consistency challenges. Correct ESI multihoming, anycast gateway behavior, and loop-avoidance design are required to prevent duplicate packets and bridging loops. Treating active/active L2 stretch as "EVPN handles it with no gateway design" understates professional DCI complexity.
