1. A method to perform traffic forwarding between geographically dispersed first site and second site, the method comprising:
receiving, by a first edge device at the first site, network traffic comprising a plurality of packets via a trunk interface of the first edge device from a virtual tunnel endpoint, the virtual tunnel endpoint having decapsulated the packets prior to communicating the packets through the trunk interface, wherein the trunk interface is configured to receive traffic originating from multiple overlay networks in communication with the first edge device at the first site; reading, by the first edge device, an overlay network identifier from each of the packets to identify a source overlay network of the received network traffic from the multiple overlay networks; modifying, by the first edge device, each of the packets to include a virtual local area network (VLAN) identifier that associates the identified source overlay network with a destination network at the second site, thereby generating modified network traffic; and forwarding, by the first edge device, the modified network traffic to a second edge device at the second site to identify the destination network based on the VLAN identifier. |
