Hi Authors,I see the following words in the introduction. " Recently, mechanisms have been defined to signal labels via link- state Interior Gateway Protocols (IGP) such as IS-IS [RFC8667]. " It's not clear to me what the " mechanisms " are. Could you please add some reference or text on this?
the reference is there - RFC8667. thanks, Peter

This draft is a work item of the Link State Routing WG of the IETF. Title : Signaling Entropy Label Capability and Entropy Readable Label Depth Using OSPF Authors : Xiaohu Xu Sriganesh Kini Peter Psenak Clarence Filsfils Stephane Litkowski Matthew Bocci Filename : draft-ietf-ospf-mpls-elc-15.txt Pages : 9 Date : 2020-06-01 Abstract: Multiprotocol Label Switching (MPLS) has defined a mechanism to load- balance traffic flows using Entropy Labels (EL). An ingress Label Switching Router (LSR) cannot insert ELs for packets going into a given Label Switched Path (LSP) unless an egress LSR has indicated via signaling that it has the capability to process ELs, referred to as the Entropy Label Capability (ELC), on that LSP. In addition, it would be useful for ingress LSRs to know each LSR's capability for reading the maximum label stack depth and performing EL-based load- balancing, referred to as Entropy Readable Label Depth (ERLD). This document defines a mechanism to signal these two capabilities using OSPFv2 and OSPFv3 and BGP-LS.
