Abstract: As described herein, a router signals a source device to establish a new stateful communication session with a destination device by changing a network path used by traffic associated with the session. In one example, a router forwards traffic of a first stateful routing session established by the source device along a first path. In response to determining that that the first path should not be used, the router forwards a packet of the first session along a second path. The destination device recognizes the change in path, which causes the destination device to reject the packet, which in turn causes the source device to establish a second stateful routing session. The router forwards subsequent traffic of the second stateful routing session along the second path.
