Abstract
Methods and apparatus for allowing a traffic level switch associated with an automatic protection switching (APS) topology to occur transparently and without reconverging routing are described. According to one aspect of the present invention, a method for providing protection switching configuration information associated with a router arrangement to includes identifying a first interface and a second interface of the router arrangement as an APS group. The method also includes providing information regarding the APS group to a process that implements a routing protocol. Providing the information regarding the group includes identifying the first interface as a primary interface and identifying the second interface as a backup interface that is arranged to protect the primary interface.
