Abstract
A network device configured to communicate with a network executes a security protocol. The security protocol establishes a secure session with a security peer network device, exchanges security protected traffic with the security peer network device over a secure link, detects whether there is a security failure in the secure session, and upon detecting a security failure, signals there is a security failure. The network device also executes a routing protocol. The routing protocol maintains a routing table that includes a route to the security peer over the secure link, routes the security protected traffic along the route, and, upon receiving from the security protocol the signal that there is a security failure, removes the route from the routing table to stop the routing.
