| 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." |
