Hi Jeff, > ERLD(Entropy Readable Label Depth)-MSD is defined in draft-ietf-isis-mpls-elc and should be used to advertise readable label stack depth. Not in a general case though. As you may remember, there were quite a few discussions around the definition of RLD/ERLD for rfc8662 & drafts isis/ospf-mpls-elc, and the (rough) consensus settled on a strict, application specific definition & usage of ERLD, not a generic RLD. -- Sergey From: mpls <mpls-bounces@ietf.org> On Behalf Of Jeff Tantsura Sent: Thursday, May 13, 2021 8:31 PM To: mpls <mpls@ietf.org>; loa Andersson <loa@pi.nu>; Stewart Bryant <stewart.bryant@gmail.com> Subject: Re: [mpls] I-D Action: draft-andersson-mpls-open-dt-questions-00.txt Loa, RFC8491/RFC8476/RFC8814 provide IGP/BGP-LS framework to signal HW capabilities wrt abilities to push/read label stacks. Please use common terminology - read instead of scan. ERLD(Entropy Readable Label Depth)-MSD is defined in draft-ietf-isis-mpls-elc and should be used to advertise readable label stack depth.

A remedy for the issues in Section 2.1.1 has been suggested, the maaximum scanning depth for each LSR in the network should be flooded to all othr LSRs and used as a constraint when setting up LSPs. Would that scale satisfactorily. Hi Loa That is a duplicate of 2.1.2 and I think we can answer that as yes. It is one additional capability field (no more than a byte) to flood and I find it hard to imagine that it would not scale.

When we find an answer amd a way to document the issu it will be removed from this document. Ideally when the Design Team is closed this document will be empty, or maybe we just add a pointer to where the answer to quesstion is documented.
