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), TCP Authentication Option (TCP-AO)) support
   capability.

   This document proposes new capability flag bits for PCE-CAP-FLAGS
   sub-TLV that can be announced as attribute in the IGP advertisement
   to distribute PCEP security support information.  In addition, this
   document updates RFC 5088 and RFC 5089 to allow advertisement of Key
   ID or Key Chain Name Sub-TLV to support TCP AO security capability.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
