Abstract
In one embodiment, a method includes identifying at a first edge device, a failure at a second edge device, the first and second edge devices located in a local network site in communication with remote network sites in an overlay network, changing a state of a routing locator address at the first edge device from down to up in response to the failure at the second edge device, the routing locator address initially associated with the second edge device, and advertising the routing locator address at the first edge device in an underlay network so that packets from the remote network sites are forwarded to the first edge device upon convergence in the underlay network. An apparatus and logic are also disclosed herein.
