Intermediate System to Intermediate System Cryptographic Authentication
RFC 3567, “Intermediate System to Intermediate System Cryptographic Authentication”, is an Informational document published in July 2003 by T. Li, R. Atkinson. It has been obsoleted by RFC 5304 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document describes the authentication of Intermediate System to Intermediate System (IS-IS) Protocol Data Units (PDUs) using the Hashed Message Authentication Codes - Message Digest 5 (HMAC-MD5) algorithm as found in RFC 2104. IS-IS is specified in International Standards Organization (ISO) 10589, with extensions to support Internet Protocol version 4 (IPv4) described in RFC 1195. The base specification includes an authentication mechanism that allows for multiple authentication algorithms. The base specification only specifies the algorithm for cleartext passwords. This document proposes an extension to that specification that allows the use of the HMAC-MD5 authentication algorithm to be used in conjunction with the existing authentication mechanisms. This memo provides information for the Internet community.
