Hi Mohit, Speaking as document shepherd. See inline.

Document: draft-ietf-isis-mpls-elc-11 Reviewer: Mohit Sethi Review Date: 2020-04-24 IETF LC End Date: 2020-05-05 IESG Telechat date: Not scheduled for a telechat Summary: This document specifies how Entropy Label Capability (ELC) and Entropy Readable Label Depth (ERLD) are advertised using IS-IS. For advertising ELC, a flag in the Prefix Attribute Flags is used. For advertising ERLD, a Node MSD Advertisement is used. Major issues: Minor issues: The document is short and straightforward. For someone like me who is not familiar with the routing area, would it make sense to explain why signalling ELC information with MPLS is not sufficient (or what are the benefits of advertising with IS-IS)? I guess I'm wondering what you mean "signaling ELC information with MPLS"? With segment routing, the IGPs can be the only choice for signaling ELC capability. I don’t believe this comment requires any action. I hope that you don't expect a gen-art reviewer to be an expert on every topic. I certainly am NOT on expert on routing. I interpreted the following text in the draft: It also introduces the concept of Entropy Label Capability (ELC) and defines the signaling of this capability via MPLS signaling protocols. to imply that signaling ELC information with MPLS is possible but this draft defines a mechanism for signaling the same information with IS-IS. Maybe the need for this is very obvious for those in the routing domain in which case ignoring my comment is perfectly fine. --Mohit Thanks, Acee Nits/editorial comments: In section 3, "used as the ECL Flag" should perhaps be "used as the ELC Flag"? In section 4, "IANA for EARLD-MSD" should perhaps be "IANA for ERLD-MSD"? In section 6, "ECL Flag (E-flag)." should perhaps be "ELC Flag (E-flag)."?
