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."

DESCRIPTION
"The number of valid route entries discarded from the

appear in the inetCidrRouteTable. One possible reason
for discarding an entry would be to free-up buffer space
for other route table entries."

DESCRIPTION
"A particular route to a particular destination, under a
particular policy (as reflected in the
inetCidrRoutePolicy object).
Dynamically created rows will survive an agent reboot.
Implementers need to be aware that if the total number
of elements (octets or sub-identifiers) in
inetCidrRouteDest, inetCidrRoutePolicy, and
inetCidrRouteNextHop exceeds 111, then OIDs of column
instances in this table will have more than 128 sub-

SNMPv2c, or SNMPv3."

DESCRIPTION
"The destination IP address of this route.
The type of this address is determined by the value of
the inetCidrRouteDestType object.
The values for the index objects inetCidrRouteDest and
inetCidrRoutePfxLen must be consistent. When the value
of inetCidrRouteDest (excluding the zone index, if one
is present) is x, then the bitwise logical-AND
of x with the value of the mask formed from the
corresponding index object inetCidrRoutePfxLen MUST be
equal to x. If not, then the index pair is not
consistent and an inconsistentName error must be
returned on SET or CREATE requests."

DESCRIPTION
"Indicates the number of leading one bits that form the

before being compared to the value in the
inetCidrRouteDest field.
The values for the index objects inetCidrRouteDest and
inetCidrRoutePfxLen must be consistent. When the value
of inetCidrRouteDest (excluding the zone index, if one

DESCRIPTION
"This object is an opaque object without any defined

the same destination. The value { 0 0 } shall be used
as the default value for this object."

DESCRIPTION
"The type of the inetCidrRouteNextHop address, as
