Technical Summary
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
replaces RFC 3567.
Working Group Summary
This is one of a series of seven documents that were originally
published as informational for historic reasons, and are being
updated to proposed standard. There is strong consensus in the
WG for this upgrade.
Document Quality
There are multiple implementations. I am not sure about deployment.
Personnel
Chris Hopps and Dave Ward have been jointly shepherding this
series of seven documents. Ross Callon is the responsible AD.
RFC Editor Note
The table in Section 5 (IANA considerations) the line that
begins "HMAC-MD5 Authentication", should reference this
document (at least in the IANA's version of the table).
