A civic VM moves from DC-East to DC-West over an EVPN-VXLAN DCI that stretches the tenant L2 VNI. Which EVPN behavior should operations expect?
Select an answer to reveal the explanation.
Short Explanation
When a VM packs up and moves across town, EVPN mobility is the change-of-address form that updates both fabrics. The MAC’s new location gets advertised so traffic stops chasing the empty rack. That is a big reason people stretch L2 with EVPN DCI carefully.
Full Explanation
With L2 VNI stretch across EVPN-VXLAN DCI, MAC mobility sequencing lets the new site advertise the MAC and remote PE/leafs converge to the new location. Mobility is not limited to a single DC when DCI stretches that overlay. Permanent sticky ownership at the old site, claiming DCI disables mobility, or requiring citywide EVPN database wipes are incorrect.
