Introduction + + The IS-IS intra-domain routing protocols, originally developed in + ISO/IEC/JTC1/SC6, have been successfully deployed in the Internet for + several years. + + + + +Zinin Informational [Page 1] + +RFC 3563 IETF - JTC1 Agreement on IS-IS July 2003 + + + ISO/IEC/JTC1/SC6 is the JTC1 sub-committee which has responsibility + for maintenance of the IS-IS standard (ISO/IEC 10589). + + The IS-IS Working Group of the IETF is chartered to develop + extensions to the IS-IS protocol to be used within the scope of the + Internet. + + This addendum documents the agreed process for the future development + of IS-IS by both organizations. + +2. Definitions + +2.1 Core IS-IS Mechanisms + + Core IS-IS Mechanisms are subsystems with associated algorithms, data + structures, and PDU formats as specified in (ISO/IEC 10589), + constituting the core of the IS-IS protocol and including the + following elements: + + a) Framework of PDU formats, including TLVs defined in [10589] + + b) Encapsulation of PDUs + + c) Adjacency state machine and formation logic + + d) DIS election algorithm + + e) Initial LSP synchronization via CSNP exchange + + f) Asynchronous LSP flooding (including DIS flooding behavior) + + g) LSP database maintenance including LSP origination, aging, and + purging + + h) Topology abstraction defined in [10589] + +2.2 Internet-specific IS-IS Extensions: + + Internet-specific IS-IS Extensions are extensions to the IS-IS + protocol that are within the work scope of the IETF including any + routing or packet forwarding technology that the IETF decides to work + on in the future (such as IPv4 or IPv6 unicast and multicast routing, + MPLS, MPLS Traffic Engineering, or Generalized MPLS), and: + + a) do not modify the Core IS-IS Mechanisms and do not change + operation of non-IP or affect compatibility with non-IP and dual + implementations of IS-IS, or + + + + +Zinin Informational [Page 2] + +RFC 3563 IETF - JTC1 Agreement on IS-IS July 2003 + + + b) add supplementary mechanisms to the Core IS-IS Mechanisms, are not + generally applicable to non-IP implementations of IS-IS, and do + not change operation of non-IP or affect compatibility with non-IP + and dual implementations of IS-IS, or + + c) are de facto implementation agreements that are not generally + applicable to non-IP implementations of IS-IS. + + Note that the introduction of new TLVs or sub-TLVs that do not modify + the algorithms of the Core Mechanisms in a way that would affect + interoperability with non-IP or dual implementations of IS-IS is not + considered to be a modification to the Core IS-IS Mechanisms. + +3. Agreement + + The following conventions are used in the rest of this document. + + SHALL This term is used to indicate commitment to follow a + specific element of this agreement. + + MUST Equivalent to "SHALL" + + SHALL NOT This phrase is used to indicate commitment to NOT perform + a specific action + + MAY This term is used to indicate the right to perform a + specific action + + SHOULD This term is used to indicate that following a specific + element of this agreement is encouraged, however there may + exist circumstances in which a decision may be made not to + do so. + +3.1 Separation of IS-IS Work Scope + + JTC1 SHALL NOT and IETF MAY (subject to the IETF standards process) + standardize any Internet-specific IS-IS Extensions. + + Any IS-IS Extensions produced within the IETF that require + standardization, but cannot be identified as Internet-specific per + section 2.2 of this document SHOULD be submitted for standardization + to JTC1 (see section 3.3.2). IETF SHALL NOT publish documents + describing such IS-IS extensions other than as Informational RFCs. + + + + + + + + +Zinin Informational [Page 3] + +RFC 3563 IETF - JTC1 Agreement on IS-IS July 2003 + + + IS-IS extensions submitted from the IETF to JTC1 will be processed + under the JTC1 fast track procedure. To ensure the quality of such + submissions, IETF SHALL apply to them the procedures for Proposed + Standard submission according to [RFC2026] (even though these + documents will not be published as standards-track IETF RFCs). + + In the situations where it is not clear from the provisions of this + document whether a specific protocol extension should be standardized + within the IETF or within JTC1, the decisions will be made on a case- + by-case basis and will be based on the agreement between the two + organizations reached via a discussion between the IETF Routing Area + Directors or the IETF liaison to JTC1/SC6 (who will reflect the IETF + consensus on the matter), and the JTC1/SC6 secretariat. + +3.2 Requirements for IS-IS-specific IETF documents + + All IS-IS-related IETF documents intended to be published as IETF + standards track RFCs MUST include a section explaining why they + qualify to be considered as Internet-specific IS-IS Extensions + described in section 2.2 of this document. + +3.3 IS-IS Registries (IANA Considerations) + +3.3.1 IS-IS TLV Codepoint Registry + + Until JTC1 provides the registry service for IS-IS, IANA is requested + to temporarily maintain such a registry as described below. Upon + notification from JTC1, the registry management authority (i.e., + value allocation) will be transferred to JTC1. IANA MAY still retain + the registry for informational purposes and keep updating it based on + information provided by JTC1. + + IANA has created and currently maintains a registry for IS-IS TLV + codepoints. The range of values is 0-255. Initial state of the + registry should be synchronized with [RFC3359]. Allocation of values + in the registry has to be approved by the designated expert assigned + by the IESG. IETF SHALL keep JTC1/SC6 informed of TLV codepoint + values allocated, and JTC1/SC6 SHALL refer allocation requests + arising within JTC1 constituencies to the IANA registry process. + +3.3.2 IETF-specific Registries + + IETF MAY request IANA to maintain IS-IS-related registries if those + are required to maintain name spaces internal to Internet-specific + IS-IS extensions. + + + + + + +Zinin Informational [Page 4] + +RFC 3563 IETF - JTC1 Agreement on IS-IS July 2003 + + +3.4 Collaboration Guidelines + +3.4.1 Learning About New Work + + IETF SHALL inform the chairman and secretariat of ISO JTC 1/SC 6 + about new IS-IS-related work items. + + JTC1/SC6 SHALL inform the IETF Routing Area directors and ISIS WG + chairs about new IS-IS-related work items. Communication MAY be + enacted directly using electronic mail, or may be conducted via + appointed SC6 / IETF liaison representatives. + +3.4.2 Submitting IETF Documents to JTC1 + + As a class A liaison organisation to JTC1, the Internet Society may + submit existing standards for adoption as International Standards of + the ISO, using the Fast-Track procedure. + + IS-IS extensions developed by IETF and intended for standardization + in JTC1 according to section 3.1 SHOULD therefore be submitted by one + of the IETF ISIS WG chairs, or an IETF Routing Area director, sending + an email message to the secretariat of ISO JTC 1 specifying the + number of the Informational RFC containing the specification (the + document MUST have been published as an RFC at the time of + submission) and requesting fast-track processing by JTC1. The full + text of the specification is then available using the following URL: + + http://www.ietf.org/rfc/rfcNNNN.txt + + where "NNNN" is the number of the RFC being submitted. The IETF + SHOULD also recommend that JTC1 assign the document to JTC1/SC6, and + SHOULD also submit to JTC1 the name of an individual who is prepared + to serve as project editor for the fast-track document. + +3.4.3 Submitting JTC1 Documents to IETF + + It is possible to make JTC1 standards specifications available for + informational purposes of the IETF community by submitting the text + of the specification as an Internet Draft and requesting the RFC + Editor to publish the document as an Informational RFC. See sections + 4.2.2 and 7 of [RFC2026] for more information. Guidelines for + Internet Draft preparation are given in [ID-GUIDE]. + +3.4.4 Mutual Document Review + + Members of ISO JTC 1/SC 6 are welcome to review any IS-IS-related + IETF document (all IETF documents are publicly available at the IETF + web site) and submit their comments to the ISIS WG (by sending an + + + +Zinin Informational [Page 5] + +RFC 3563 IETF - JTC1 Agreement on IS-IS July 2003 + + + email to the working group mailing list), the ISIS WG chairs (see + [ISISWG] for more information), the IETF Routing Area directors, or + the IESG (iesg@ietf.org). + + JTC1 is encouraged to request an IETF review of IS-IS-related work + performed by JTC 1/SC 6 by submitting the text of the document as an + informational Internet Draft (see section 3.3.2) and sending a + message to the IETF ISIS WG mailing list requesting the comments. + + The IETF MAY request JTC1 to circulate provided comments among the + National Bodies and Liaison Organizations involved in the discussion + of the work under review. + +4.
