Abstract
Extensions to the Path Computation Element Communication Protocol(PCEP) to support stateful Path Computation Elements (PCEs) aredefined in RFC 8231. One of the extensions is the Stateful PCERequest Parameters (SRP) object. That object includes a Flags fieldthat is a set of 32 bit flags, and RFC 8281 defines an IANA registryfor tracking assigned flags. However, RFC 8231 does not explain howan implementation should set unassigned flags in transmittedmessages, nor how an implementation should process unassigned,unknown, or unsupported flags in received messages.
This document updates RFC 8231 by defining the correct behaviors.
