Hi, All IDR experts:

We updated the draft, which are mainly aligned with the contents within
https://datatracker.ietf.org/doc/html/draft-wang-lsr-stub-link-attributes-06
for Native IP scenario.
Two additional new TLVs are defined, they are  "Stub Link IPv4 Prefix" and
"Stub Link IPv6 Prefix" respectively.

We also give some suggestions for the IANA allocated values of newly
proposed values, expect the IANA can assign them temporarily for the
implementations.
Comments are welcome.

Best Regards

Aijun Wang

A New Internet-Draft is available from the on-line Internet-Drafts
directories. This Internet-Draft is a work item of the Inter-Domain Routing
(IDR) WG of the IETF.

   Title           : BGP-LS Extension for Inter-AS Topology Retrieval
   Authors         : Aijun Wang
                     Huaimo Chen
                     Ketan Talaulikar
                     Shunwan Zhuang
   Filename        : draft-ietf-idr-bgpls-inter-as-topology-ext-13.txt
   Pages           : 13
   Date            : 2023-04-03

Abstract:
   This document describes the process to build Border Gateway Protocol-
   Link State (BGP-LS) key parameters in inter-domain scenario, defines
   one new BGP-LS Network Layer Reachability Information (NLRI) type
   (Stub Link NLRI) and some new Type-Length-Values (TLVs) for BGP-LS to
   let Software Definition Network (SDN) controller retrieve the network
   topology automatically under various inter-AS environments.

   Such extension and process can enable the network operator to collect
   the interconnect information between different domains and then
   calculate the overall network topology automatically based on the
   information provided by BGP-LS protocol.
