Hi Uma, There was a discussion on this topic. I think this was agreed during Chicago's IETF if I remember correctly. The outcome of the discussion was that if an implementation is able to read N labels, this does not mean that it is actually able to hash based on these N labels. So we needed something which combines the ability of reading + doing an action. That's why the ERLD has been defined instead of the base RLD which was foreseen at first stages of the draft. This implies that there is a possibility to create additional RLDs that may have other applications than entropy.
Brgds, From: Lsr [mailto:lsr-boun...@ietf.org] On Behalf Of Uma Chunduri Sent: Wednesday, August 28, 2019 20:38 To: lsr@ietf.org 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. _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
