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.
