[Qin]: I think the importance of this discovery is in the deployments which allow multiple choices for security credentials. without such discovery, it leads to unexpected failure or additional message exchange is needed to indicate error to PCC using PCErr message. >I am asking this in particular as scope is MD, AO and TLS. >Also I see PCE has to be part of the IGP here, whereas I see >draft-ietf-pce-pceps doesn't mandate this (does it??) [Qin]: That is correct, draft-ietf-pce-pceps doesn't need to couple with IGP discovery, draft-ietf-pce-pceps may leverage other discovery mechanism, e.g., DNS based PCE discovery mechanism. More later. -- Uma C. -----Original Message----- From: Pce [mailto:[email protected]] On Behalf Of Qin Wu Sent: Wednesday, August 27, 2014 3:10 AM To: [email protected] Subject: Re: [Pce] I-D Action: draft-wu-pce-discovery-pceps-support-01.txt Hi, Here is the update to draft-wu-pce-discovery-pceps-support-01. The most changes are editorial changes. The diff is: http://www.ietf.org/rfcdiff?url2=draft-wu-pce-discovery-pceps-support-01 This draft provides a mechanism for PCC to discover PCE with TLS support. In addition, the draft also support discovery of PCE server with MD support, TCP-AO support respectively. Authors feel it will be a good to have this draft separately rather than simply merging into draft-ietf-pce-pceps. Any opinions or objection?

Title : IGP extension for PCEP security capability support in the PCE discovery Authors : Diego R. Lopez Qin Wu Dhruv Dhody Daniel King Filename : draft-wu-pce-discovery-pceps-support-01.txt Pages : 6 Date : 2014-08-13 Abstract: 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 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 PCEP security (e.g., Transport Layer Security(TLS)) support capability. This document proposes new capability flag bit for PCE-CAP-FLAGS sub- TLV that can be announced as attribute in the IGP advertisement to distribute PCEP security support information.
