1. Introduction

This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines Textual Conventions used in Virtual Private
Networks (VPNs) and IETF VPN-related MIBs.

1.1. Conventions Used in This Document

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 [RFC2119].

2. The Internet-Standard Management Framework

For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].

Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].

3. VPN-TC-STD-MIB

3.1. Description

The VPN-TC-STD-MIB defines a Textual Convention for the Global VPN
Identifier, or VPN-ID, as specified in [RFC2685]. The purpose of a
VPN-ID is to uniquely identify a VPN. It MUST be 7 octets in length,
and SHOULD be comprised of a 3 octet Organizationally Unique
Identifier (OUI) that uniquely identifies the VPN Authority, followed
by a 4 octet value assigned by the VPN Authority that uniquely
identifies the VPN within the context of the OUI.

DESCRIPTION
"This MIB contains TCs for VPNs.

Copyright (C) The Internet Society (2005). This version
of this MIB module is part of RFC 4265; see the RFC
itself for full legal notices."
-- Revision history.
REVISION "200511150000Z" -- 15 November 2005
DESCRIPTION "Initial version, published as RFC 4265."
::= { mib-2 129 }

-- definition of textual conventions

VPNId ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The purpose of a VPN-ID is to uniquely identify a VPN.
The Global VPN Identifier format is:
3 octet VPN Authority, Organizationally Unique Identifier
followed by 4 octet VPN index identifying VPN according
to OUI"
REFERENCE
"Fox, B. and Gleeson, B., 'Virtual Private Networks
Identifier', RFC 2685, September 1999."
SYNTAX OCTET STRING (SIZE (7))

VPNIdOrZero ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"This textual convention is an extension of the
VPNId textual convention that defines a non-zero-length
OCTET STRING to identify a physical entity. This extension
permits the additional value of a zero-length OCTET STRING.

Schliesser & Nadeau Standards Track [Page 3]

RFC 4265 VPN-TC-STD-MIB November 2005

The semantics of the value zero-length OCTET STRING are
object-specific and must therefore be defined
as part of the description of any object that uses this
syntax. Examples of usage of this extension are
situations where none or all VPN IDs need to be
referenced."
SYNTAX OCTET STRING (SIZE (0 | 7))

END

4. Security Considerations

This module does not define any management objects. Instead, it
defines a set of textual conventions that may be used by other MIB
modules to define management objects.

Meaningful security considerations can only be written in the MIB
modules that define management objects. Therefore, this document has
no impact on the security of the Internet.

5. IANA Considerations for VPN-TC-STD-MIB

The IANA has assigned { mib-2 129 } to the VPN-TC-STD-MIB module
specified in this document.
