Abstract
This document pre-allocates the fixed Pseudo-wire identifier , and
other fixed protocol values for protocols defined primarily in the
pseudo wire edge to edge working group. ( PWE3 ) Detailed IANA

1. Specification of Requirements
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119
2. IANA Considerations
Unless otherwise noted in this document, the value of 0 is reserved,
and MUST not be used.
2.1. MPLS Pseudowire Type
IANA needs to set up a registry of "MPLS Pseudowire Type". These are
15-bit values. PW Type values 1 through 30 are specified in this
document, PW Type values 31 through 1024 are to be assigned by IANA,
using the "Expert Review" policy defined in [RFC2434]. PW Type values
1025 through 4096, 0, and 32767 are to be allocated using the IETF
consensus policy defined in [RFC2434]. PW Type values 4097 through
32766 are reserved for vendor proprietary extensions and are to be
assigned by IANA, using the "First Come First Served" policy defined
in RFC2434. A Pseudowire Type description of up to 65 characters is
required for any assignment from this registry.

Note 1: This PW type is grandfathered for a historical protocol. The
recommended standards-track protocol to use is CEP (PW type 0x0010).
2.2. Interface Parameters Sub-TLV type
IANA needs to set up a registry of "Pseudowire Interface Parameter
Sub-TLV types". These are 8 bit values. Sub-TLV types 1 through 12
are specified in this document. Sub-TLV types 13 through 64 are to be
assigned by IANA, using the "Expert Review" policy defined in
RFC2434. Sub-TLV types 65 through 127, 0, and 255 are to be allocated
using the IETF consensus policy defined in [RFC2434]. Sub-TLV types
values 128 through 254 are reserved for vendor proprietary extensions

Internet Draft draft-ietf-pwe3-iana-allocation-13.txt October 2005
and are to be assigned by IANA, using the "First Come First Served"
policy defined in RFC2434.
Any assignments requested from this registry require a description up
to 54 characters.
For each allocation a length field MUST also be specified as follows:
- A decimal integer
- Text as follows:"up to X", where X is a decimal integer
- Up to 3 different decimal integers.
is also required for assignment from this registry.
Initial Pseudowire Interface Parameter Sub-TLV type allocations are
specified below:
Parameter ID Length Description
0x01 4 Interface MTU in octets
0x02 4 Maximum Number of concatenated ATM cells
0x03 up to 82 Optional Interface Description string
0x04 4 CEP/TDM Payload Bytes
0x05 4 CEP options
0x06 4 Requested VLAN ID

0x0F Variable Length IPV6CP [RFC2472]
Note that the Length field is defined as the length of the Sub-TLV
including the Sub-TLV type and length field itself.
2.3. Attachment Identifiers
2.3.1. Attachment Individual Identifier Type
IANA needs to set up a registry of "Attachment Individual Identifier
(AII) Type". These are 8-bit values. AII Type value 1 is defined in
this document. AII Type values 2 through 64 are to be assigned by
IANA using the "Expert Review" policy defined in RFC2434. AII Type
values 65 through 127, 0, and 255 are to be allocated using the IETF
consensus policy defined in [RFC2434]. AII types values 128 through
254 are reserved for vendor proprietary extensions and are to be
assigned by IANA, using the "First Come First Served" policy defined

Type". These are 8-bit values. AGI Type value 1 is defined in this
document. AGI Type values 2 through 64 are to be assigned by IANA
using the "Expert Review" policy defined in RFC2434. AGI Type values
65 through 127, 0, and 255 are to be allocated using the IETF
consensus policy defined in [RFC2434]. AGI types values 128 through
254 are reserved for vendor proprietary extensions and are to be

2.4. Pseudo Wire Status
IANA needs to set up a registry of "Pseudowire Status Codes". These
are bitstrings of length 32. Status bits 0 to 4 are defined in this
document. Status bits 5 to 31 are to be assigned by IANA using the
"Expert Review" policy defined in RFC2434.
Any requests for allocation from this registry must include a

description up to 65 characters.

3. Security Considerations
This document specifies only fixed identifiers, and not the protocols
used to carry the encapsulated packets across the network. Each such
protocol may have its own set of security issues, but those issues
are not affected by the identifiers specified herein.
