1. A method comprising:
adding a specific route for an Internet Protocol (IP) address that is associated with a first workload into a routing table for a first network device in a first site based on detecting the first workload migrated from a second site to the first site, the first network device having an IP address that is the same as the IP address of a second network device in the second site;
receiving, by the first network device, a packet from a second workload that includes a destination address for the first workload;
determining that destination address of the packet matches the specific route in the routing table for the first workload; and
based on determining that destination address of the packet matches the specific route in the routing table for the first workload, routing the packet from the second workload to the first workload using the specific route in the routing table without sending the packet to the second site.
