RFC 8231 describes a set of extensions to the Path Computation Element Communication Protocol (PCEP) to enable stateful control of MPLS-TE and GMPLS Label Switched Paths (LSPs) via PCEP. One of the extensions is the LSP object, which includes a Flag field with a length of 12 bits. However, all bits of the Flag field have already been assigned.
This document defines a new LSP-EXTENDED-FLAG TLV for the LSP object for an extended Flag field.
For the definition of Status, see RFC 2026.
For the definition of Stream, see RFC 8729.
