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 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.

   This document defines capability flag bits for the PCE-CAP-FLAGS sub-
   TLV that can be announced as an 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 a
   Key ID or Key Chain Name Sub-TLV to support TCP-AO security
   capability.  Further, this document updates RFC 8231 and RFC 8306.
