A municipal VXLAN runbook needs a sensible first-pass order when overlay traffic fails between leaves. Which sequence best structures troubleshooting?
Select an answer to reveal the explanation.
Short Explanation
Fix the road, then the hallway membership, then whether the host badge was learned—underlay → VTEP/VNI → MAC table. That order stops you from chasing ghosts in Wireshark on the wrong continent. City runbooks love a boring, repeatable sequence.
Full Explanation
Effective VXLAN triage starts with underlay IP reachability between VTEPs, because encapsulation cannot succeed without it. Next, confirm the VNI is mapped and joined to the fabric’s replication/control mechanisms on both sides. Finally, inspect MAC/IP learning and host attachment state. Jumping first to wholesale EVPN wipes or Internet-edge captures skips the structured dependencies of the overlay data plane.
