[secdir] SecDir review of draft-ietf-isis-rfc4971bis-01

[Yaron Sheffer <[e-mail]>]

I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the IESG.
These comments were written primarily for the benefit of the security
area directors.  Document editors and WG chairs should treat these
comments just like any other last call comments.

This document is a minor update to RFC4971, in order to correctly
support IPv6-only routers.

Summary

The document is ready for publication.

Details

The Security Considerations are unchanged from the original RFC and
cover the router capability feature reasonably. They still seem to
describe this quaint world where each router can rely on all its peers
to always send correct information. But at least we recommend to use
protocol-level integrity mechanisms in "high risk" situations.

Thanks,
