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.
