In one embodiment, an apparatus includes a controller configured for operation in an active automatic protection switching (APS) mode and an inactive APS mode and a processor operable when the controller is in the active mode to transmit a synchronization message to a corresponding APS node. The synchronization message includes state information for a connection with a peer node. The processor is further operable when the controller is in inactive mode to receive the synchronization message from the corresponding APS node, switch the controller from inactive mode to active mode upon receiving notification of a failure from the corresponding APS node, and establish a connection with the peer node without negotiating the connection with the peer node. Methods for synchronization of state information to reduce APS switchover time are also disclosed.
