Generalized MPLS (GMPLS) Traffic Engineering (TE) Label Switched Paths (LSPs) can be route constrained by making use of the Explicit Route Object (ERO) and related subobjects as defined in [RFC3209], [RFC3473], [RFC3477], [RFC4873], [RFC4874], [RFC5520], and [RFC5553]. Several documents have identified the need for attributes that can be targeted at specific hops in the path of an LSP, including [RFC6163], [WSON-SIG], [RFC7571], or [OBJ-FUN]. This document provides a generic mechanism for use by these other documents.

This document defines an extension to the RSVP Explicit Route Object (ERO) and Record Route Object (RRO) to allow them to specify or record generic attributes that apply to a given hop.
