Abstract
In some embodiments, a first network device in a first site sets a first IP address for an interface of the first network device to a value of a second IP address of a second network device in a second site. Policies are added in a policy table to cover IP addresses used in the second site and a specific route for a third IP address associated with a first workload migrated from the second site to the first site is added into a routing table. The first workload is on a stretched network that is coupled via a layer 2 channel. The policy table configures the first network device to send a second packet from the first workload to a third workload in the second site via the layer 2 channel when an IP address for the third workload does not match an eligible route in the routing table.
