  • Route convergence based on ethernet operations, administration, and maintenance protocol
    Patent number: 8605603
    Abstract: In an example embodiment, a method of route convergence is provided. In this method, a loss of connectivity is detected along a communication route by way of an Ethernet Operations, Administration, and Maintenance (OAM) protocol. Examples of Ethernet OAM protocols include Connectivity Fault Management protocol and Ethernet Local Management Interface protocol. Thereafter, a data link layer identifier associated with the communication route is identified and this data link layer identifier is mapped to a network layer address. Convergence on an alternate communication route can then be based on the mapped network layer address.
