Abstract
An apparatus and method for managing multiple traffic redundancy mechanisms includes a resource manager for managing the multiple redundancy mechanisms for bridging traffic between a working port and a protection port, and uses an agent for the working port in order to maintain routes associated with the working port even after a failure occurs that affects communication over the working port. The resource manager creates a protection group including the working port and the protection port. A traffic bridge is established between the working port and the protection port.
