Abstract: Communication path redundancy protection systems and methods are disclosed. Multiple communication interfaces having a common address support communications on respective communication paths. One of the interfaces or communication paths is selected as an active interface or path for transferring communication traffic. In the event of a fault associated with the active interface or path, another one of the interfaces or paths is selected to become active. The common address allows redundant interfaces to appear as a single interface to other communication equipment, whereas the multiple interfaces provide redundant path protection using a single piece of communication equipment. When embodiments of the invention are implemented in a gateway router of a core communication network, for example, activity switches between redundant access paths have no effect on routing in the core network.
