IS-IS Registry Extension for Purges
RFC 6233, “IS-IS Registry Extension for Purges”, is a Proposed Standard document published in May 2011 by T. Li, L. Ginsberg. It updates RFC 3563, RFC 5304, RFC 5310. The canonical text is published by the RFC Editor.
Abstract
IANA maintains the "IS-IS TLV Codepoints" registry. This registry documents which TLVs can appear in different types of IS-IS Protocol Data Units (PDUs), but does not document which TLVs can be found in zero Remaining Lifetime Link State PDUs (LSPs), a.k.a. purges. This document extends the existing registry to record the set of TLVs that are permissible in purges and updates the rules for generating and processing purges in the presence of authentication. This document updates RFC 3563, RFC 5304, and RFC 5310. [STANDARDS-TRACK]
