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 internet-draft intends to obsolete RFC 6326, which describes Transparent Interconnection
of Lots of Links (TRILL) Use ofIntermediate System to Intermediate System (IS-IS).

The security considerations section does exist and refers to the TRILL base protocol, RFC
6325, for its guidance.  The section then states that the draft introduces no new security
considerations when using IS-IS given that IS-IS authentication (as specified in RFC 5304 and 5310)
can be used to secure its protocol messaging specified in the draft.  I believe that this is true
and don't see any other security concerns from what has been outlined and the changes from the base
specification.

General comments:

None.

Editorial comments:

None.

Shawn.
