    DESCRIPTION
           "The MIB module for the management of CIDR multipath IP
            Routes.

Copyright (C) The Internet Society (2006).  This version
            of this MIB module is a part of RFC 4292; see the RFC
            itself for full legal notices."

REVISION      "200602010000Z"
    DESCRIPTION
           "IPv4/v6 version-independent revision.  Minimal changes
            were made to the original RFC 2096 MIB to allow easy
            upgrade of existing IPv4 implementations to the
            version-independent MIB.  These changes include:

Adding inetCidrRouteDiscards as a replacement for the
            deprecated ipRoutingDiscards and ipv6DiscardedRoutes
            objects.

Adding a new conformance statement to support the
            implementation of the IP Forwarding MIB in a
            read-only mode.

The inetCidrRouteTable replaces the IPv4-specific
            ipCidrRouteTable, its related objects, and related
            conformance statements.

Published as RFC 4292."
