        DESCRIPTION
             "This document describes a management information base for
             the IS-IS Routing protocol, as described in ISO 10589,
             when it is used to construct routing tables for IP
             networks, as described in RFC 1195.

             This document is based on a 1994 IETF document by Chris
             Gunner.  This version has been modified to include
             current syntax, to exclude portions of the protocol that
             are not relevant to IP, and to add management support for
             current practice.

             Copyright (C) The Internet Society (2006).  This version
             of this MIB module is part of RFC 4444; see the RFC
             itself for full legal notices."
