Hi all,
I have reviewed draft-ietf-lsr-pce-discovery-security-support-10 as part of the
Operational directorate's ongoing effort to review all IETF documents being
processed by the IESG. These comments were written with the intent of
improving the operational aspects of the IETF drafts. Comments that are not
addressed in last call may be included in AD reviews during the IESG review.
Document editors and WG chairs should treat these comments just like any other
last call comments.
“When a Path Computation Element (PCE) is a Label Switching Router
(LSR) participating in the Interior Gateway Protocol (IGP), or even a
server participating in the IGP, its presence and path computation
capabilities can be advertised using IGP flooding. The IGP
extensions for PCE discovery (RFC 5088 and RFC 5089) define a method
to advertise path computation capabilities using IGP flooding for
OSPF and IS-IS respectively. However these specifications lack a
method to advertise PCE Communication Protocol (PCEP) security (e.g.,
Transport Layer Security (TLS), TCP Authentication Option (TCP-AO))
support capability.”
My overall view of the document is almost 'Ready' for publication, except some
