Routing Information Protocol
     
        1.  (RIP) A {distance vector}, as opposed to {link
        state}, {routing} {protocol}.  RIP is an {Internet} {standard}
        {Interior Gateway Protocol} defined in {STD} 34, {RFC 1058}
        and updated by {RFC 1388}.
     
        See also {Open Shortest Path First}.
     
        2.  (RIP) A companion {protocol} to {IPX} for
        exchange of {routing} information in a {Novell} {network}.
        RIP has been partly superseded by {NLSP}.  It is not related
        to the {Internet} protocol of the same name.
