- DESCRIPTION
- "The MIB module for the management of CIDR multipath IP
- Routes.
- Copyright (C) The Internet Society (2004). This version
- of this MIB module is a part of RFC xxxx; see the RFC
- itself for full legal notices."
- -- RFC Ed : replace xxxx with actual RFC number & remove note
- REVISION "200402091200Z"
- 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 xxxx."
