The municipal NOC needs to confirm a leaf can source and reach VXLAN traffic as a VTEP. Which verification focus is most appropriate?
Select an answer to reveal the explanation.
Short Explanation
No return address on the truck, no delivery. Confirm the leaf’s VTEP source IP is configured and that the underlay can reach the far VTEP. Pretty LLDP banners don’t move VXLAN packets.
Full Explanation
A VTEP must own a stable source IP (often a loopback) used as the outer address for VXLAN encapsulation. Operators should verify that address is configured, advertised into the underlay, and reachable from remote VTEPs. Without that reachability, overlay tunnels or next-hops will not function even if VNIs exist. Civic NOC checklists typically place VTEP IP and underlay ping/traceroute early in VXLAN health checks.
