Abstract
In some embodiments, a method receives, by a first network device, a packet from a first workload that is located in first site. The first site includes stretched networks across a second site and a third site. The packet includes a destination IP address for a device in the second site. The method determines that the destination IP address does not match an eligible route in a routing table. The first workload was migrated from the second site to the first site and is located on a stretched network between the first site and the second site. A site identifier associated with the first workload is determined where the site identifier identifies the second site. The method selects a site policy based on the site identifier and uses the site policy to send the packet through a layer 2 channel to the second network device in the second site.
