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.
