1. A method for dynamically exchanging or updating routing capabilities between neighboring peer routers in a computer network, the method comprising the steps of:

  • establishing a peer connection between one of the neighboring routers and another of the neighboring routers;

    announcing the ability to support a new capability, or revise or remove a previously announced capability, from the one of the neighboring routers to the other of the neighboring routers while the peer connection is established; and

    exchanging a capability message between the one of the neighboring routers and the other of the neighboring routers to thereby facilitate graceful capability changes between the routers without terminating the peer connection.
