An engineer configures the municipal interconnect overlay but sources VXLAN from the wrong VTEP address on the DCI-facing device. What is the likely result?
Select an answer to reveal the explanation.
Short Explanation
VXLAN cares which address you claim as the tunnel endpoint—like putting the wrong return address on every package. If the DCI device sources from the wrong VTEP, remote borders will not line up with what EVPN advertised. Fix the VTEP identity on the interconnect overlay.
Full Explanation
DCI overlays depend on correct VTEP addressing so remote PE/borders encapsulate toward the address associated with EVPN next hops. A mismatched source breaks data-plane consistency even if some BGP sessions exist. EVPN does not silently rewrite an arbitrary wrong source; random interface IPs are not interchangeable VTEP identities; LLDP is unrelated to UDP 4789 path correctness.
