       DESCRIPTION

               "This data type is used as the syntax of the ifType

               object in the (updated) definition of MIB-II's

               ifTable.

               The definition of this textual convention with the

               addition of newly assigned values is published

               periodically by the IANA, in either the Assigned

               Numbers RFC, or some derivative of it specific to

               Internet Network Management number assignments.  (The

               latest arrangements can be obtained by contacting the

               IANA.)

               Requests for new values should be made to IANA via

               email (iana&iana.org).

               The relationship between the assignment of ifType

               values and of OIDs to particular media-specific MIBs

               is solely the purview of IANA and is subject to change

               without notice.  Quite often, a media-specific MIB's

               OID-subtree assignment within MIB-II's 'transmission'

               subtree will be the same as its ifType value.

               However, in some circumstances this will not be the

               case, and implementors must not pre-assume any

               specific relationship between ifType values and

               transmission subtree OIDs."

IANAtunnelType ::= TEXTUAL-CONVENTION

    STATUS     current

    DESCRIPTION

            "The encapsulation method used by a tunnel. The value

            direct indicates that a packet is encapsulated

            directly within a normal IP header, with no

            intermediate header, and unicast to the remote tunnel

            endpoint (e.g., an RFC 2003 IP-in-IP tunnel, or an RFC

            1933 IPv6-in-IPv4 tunnel). The value minimal indicates

            that a Minimal Forwarding Header (RFC 2004) is

            inserted between the outer header and the payload

            packet. The value UDP indicates that the payload

            packet is encapsulated within a normal UDP packet

            (e.g., RFC 1234).

            The values sixToFour, sixOverFour, and isatap

            indicates that an IPv6 packet is encapsulated directly

            within an IPv4 header, with no intermediate header,

            and unicast to the destination determined by the 6to4,

            6over4, or ISATAP protocol.

            The remaining protocol-specific values indicate that a

            header of the protocol of that name is inserted

            between the outer header and the payload header.

            The assignment policy for IANAtunnelType values is

            identical to the policy for assigning IANAifType

            values."
