Abstract
The embodiments herein push notifications to network devices used by a shared service to which a roaming host in a network fabric is subscribed. For example, a network fabric controller can access a VN policy table which stores the relationships between the virtual networks in the network fabric. Using this table, the controller can identify what shared service VNs (i.e., extranets) can communicate with the host's VN. The controller can push out notifications to the network devices used by the shared service VNs to store the new location of the host. That is, the network devices that locally store a location of the host can update their routing caches to point to the new location of the host. In this manner, the network fabric can reduce the time needed to reconverge on the new location of the host by updating the network devices used by the shared service VNs.
