    DESCRIPTION
            "The MIB module for management of IP Tunnels,
            independent of the specific encapsulation scheme in
            use.

Copyright (C) The Internet Society (2005).  This
            version of this MIB module is part of RFC 4087;  see
            the RFC itself for full legal notices."

REVISION     "200505160000Z" -- May 16, 2005
    DESCRIPTION
            "IPv4-specific objects were deprecated, including
            tunnelIfLocalAddress, tunnelIfRemoteAddress, the
            tunnelConfigTable, and the tunnelMIBBasicGroup.

Added IP version-agnostic objects that should be used
            instead, including tunnelIfAddressType,
            tunnelIfLocalInetAddress, tunnelIfRemoteInetAddress,
            the tunnelInetConfigTable, and the
            tunnelIMIBInetGroup.

The new tunnelIfLocalInetAddress and
            tunnelIfRemoteInetAddress objects are read-write,
            rather than read-only.

Updated DESCRIPTION clauses of existing version-
            agnostic objects (e.g., tunnelIfTOS) that contained
            IPv4-specific text to cover IPv6 as well.

Added tunnelIfFlowLabel for tunnels over IPv6.

The encapsulation method was previously an INTEGER
            type, and is now an IANA-maintained textual
            convention.

Published as RFC 4087."

            "The status of this row, by which new entries may be
            created, or old entries deleted from this table.  The
            agent need not support setting this object to
            createAndWait or notInService since there are no other
            writable objects in this table, and writable objects
            in rows of corresponding tables such as the
            tunnelIfTable may be modified while this row is
            active.

To create a row in this table for an encapsulation
            method which does not support multiple parallel
            tunnels with the same endpoints, the management
            station should simply use a tunnelConfigID of 1, and
            set tunnelConfigStatus to createAndGo.  For
            encapsulation methods such as L2F which allow multiple
            parallel tunnels, the management station may select a
            pseudo-random number to use as the tunnelConfigID and
            set tunnelConfigStatus to createAndGo.  In the event
            that this ID is already in use and an
            inconsistentValue is returned in response to the set
            operation, the management station should simply select
            a new pseudo-random number and retry the operation.

Creating a row in this table will cause an interface
            index to be assigned by the agent in an
            implementation-dependent manner, and corresponding
            rows will be instantiated in the ifTable and the
            tunnelIfTable.  The status of this row will become
            active as soon as the agent assigns the interface
            index, regardless of whether the interface is
            operationally up.

Deleting a row in this table will likewise delete the
            corresponding row in the ifTable and in the
            tunnelIfTable.

            created, or old entries deleted from this table.  The
            agent need not support setting this object to
            createAndWait or notInService since there are no other
            writable objects in this table, and writable objects
            in rows of corresponding tables such as the

            active.

To create a row in this table for an encapsulation
            method which does not support multiple parallel
            tunnels with the same endpoints, the management
            station should simply use a tunnelInetConfigID of 1,
            and set tunnelInetConfigStatus to createAndGo.  For
            encapsulation methods such as L2F which allow multiple
            parallel tunnels, the management station may select a
            pseudo-random number to use as the tunnelInetConfigID
            and set tunnelInetConfigStatus to createAndGo.  In the
            event that this ID is already in use and an
            inconsistentValue is returned in response to the set
            operation, the management station should simply select
            a new pseudo-random number and retry the operation.

            active as soon as the agent assigns the interface
            index, regardless of whether the interface is

Deleting a row in this table will likewise delete the
            corresponding row in the ifTable and in the
