Abstract:
Techniques disclosed herein provide a method for configuring a network in DCI environment. An EVPN session is established between a first gateway device of a first network, and a second gateway device of a second network that are linked by L2 DCI link. An ESI is allocated for that EVPN session. A label is created for every combination of the ESI and media access control virtual routing and forwarding table (MAC VRF) that is locally configured at the first gateway device. An EVPN path is received for a host in the first network that is associated with MAC VRF. The path in imported the first MAC VRF by the first gateway device and exported via the inter-DCI EVPN session. The second gateway device identifies a label for MAC and re-exports it in local EVPN session with the identified label.
