After a change window, a city engineer verifies EVPN overlay health. Beyond interface counters, what should that verification emphasize?
Select an answer to reveal the explanation.
Short Explanation
Interface counters tell you the road still has asphalt; EVPN checks tell you the street signs and tunnels still line up. After a change, look at sessions, EVPN routes, and VTEP reachability—not just green link lights. Rack-door paint and printer leases will not prove the overlay is healthy.
Full Explanation
Post-change validation in an EVPN-VXLAN fabric must include overlay and control-plane checks: EVPN peering or signaling health, expected EVPN routes, and VTEP/tunnel reachability—not merely physical interface counters. Interface stats alone can look healthy while overlay state is broken. Facility aesthetics, unrelated printer DHCP, or UPS age do not substitute for those fabric-specific monitors.
