Thank you for the update.   

I would like to solicit your help to move along this draft and BGP-LS drafts
in the future.   We are looking for a set of IDR participants who are
familiar with BGP-LS to form a review team in IDR.

No updates in this draft. 

During IETF103 in Bangkok the aspect of ERLD was discussed in a corridor
meeting. The base consideration was that there is interest to extend ERLD
meaning beyond pure node value, particular for the inter-as use-case, where
the operator would like to expose ERLD per prefix. 

The BGP-LS draft to encode the ERLD is on-hold until the updates in the IGP
(OSPF/ISIS/OSPFv3) signaling drafts materialized, so that correct encoding
in BGP-LS can be documented.

   This document defines the attribute encoding to use for BGP-LS to
   expose ERLD "Entropy capable Readable Label Depth" from a node to a
   centralised controller (PCE/SDN).
