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."
