Technical Summary
Extensions to the Path Computation Element communications Protocol
(PCEP) to support stateful Path Computation Elements (PCEs) are
defined in RFC 8231. One of the extensions is the Stateful PCE
Request Parameters (SRP) object. That object includes a Flags field
that is a set of 32 bit flags, and RFC 8281 defines an IANA registry
for tracking assigned flags. However, RFC 8231 does not explain how
an implementation should set unassigned flags in transmitted
messages, nor how an implementation should process unassigned,
unknown, or unsupported flags in received messages.
This document updates RFC 8231 by defining the correct behaviors.
Working Group Summary
This I-D being a very focused and uncontroversial fix, it has been moved
directly from individual draft to WGLC and submitted to the AD. Based
on the direction from the AD, the file name was changed to reflect the
WG output and to garner more visibility within the WG.
Document Quality
A private and unscientific poll of implementers of RFC 8231 conducted
by the author suggests that existing implementations already abide by
the modification set out in this document.
