         A {protocol} used to automatically agree upon
        {encapsulation} format options, handle varying packet size
        limits, authenticate the identity of its {peer} on the link,
        determine when a link is functioning properly and when it is
        defunct, detect a looped-back link and other common
        misconfiguration errors, and terminate the link.
