Acee – I do understand the question – and I believe the reference I cited provides the answer. You need to read the referenced draft.
If you have a cogent argument why it is safe to assume that the combination of actions required to support EL translate to any other type of activity that might be required on a label stack, please make it. Then Uma’s suggestion might make sense.

Thanx. Les From: Lsr <[email protected]<mailto:[email protected]>> On Behalf Of Uma Chunduri Sent: Wednesday, August 28, 2019 11:38 AM To: [email protected]<mailto:[email protected]> Subject: [Lsr] draft-ietf-isis-mpls-elc-07 Can anybody tell what was the conclusion (if any) in previous discussions in various WGs on why the readable label depth in an LSR has to be entropy label specific ? IOW can we just modify this as “readable label depth” as opposed to “entropy readable label depth” ? This would allow any other special purpose label inserted in the stack and would be at par with current MSD type “Base MPLS Imposition MSD” ( https://www.iana.org/assignments/igp-parameters/igp-parameters.xhtml ). -- Uma C.
