Abstract
Presented herein are techniques to enable seamless mobility of hosts (endpoints) between disaggregated Ethernet virtual private network (EVPN) domains that are connected with one another by an external network (e.g., a Wide-Area Network (WAN)). In one example, a leaf node in the first domain, which was previously connected to a host, receives updated routing information for the host. The leaf node performs a local host verification process to confirm that the host has moved and, in response to confirming that that the host has moved, the first leaf node sends a targeted host announcement message to the host in the second domain.
