Control Protocol (LCP).
The LCP is used to automatically agree upon the encapsulation format options, handle varying limits on sizes of packets, detect a loopedback link and other common misconfiguration errors, and terminate the link. Other optional facilities provided are authentication of the identity of its peer on the link, and determination when a link is functioning properly and when it is failing.
