The IESG has approved the following document: - 'IS-IS Extended Sequence number TLV' (draft-ietf-isis-extended-sequence-no-tlv-06.txt) as Proposed Standard This document is the product of the IS-IS for IP Internets Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-isis-extended-sequence-no-tlv/ Technical Summary This document defines Extended Sequence number TLV to protect Intermediate System to Intermediate System (IS-IS) PDUs from replay attacks. Working Group Summary There was initial resistance by some members of the WG with regard to the need for the new mechanism. Consensus over the need was achieved, while a technical objection remained over the inclusion of the extended sequence number TLV in LSP PDUs as they already contain a sequence number. The new sequence number TLV was removed from the LSP which dealt with the technical objection. Document Quality No known implementations currently exist. One vendor has expressed interest in implementing the mechanism for use in DC/TRILL deployments. Les Ginsberg did multiple in-depth reviews of the document with comments which were incorporated, and is acknowledged in the document.
