Hi, All:


We just uploaded one draft at
to describe the BGP-LS extension for inter-as topology retrieval in
different scenarios.

We are also applying the time slot on the upcoming IETF 101 meeting to
present this topic. Any comments are welcome.


The abstracts of this draft are the followings:

This document describes new TLVs extended for BGP-LS to transfer the
originator of redistributed routes and other inter-AS TE related TLVs to let
the SDN controller to retrieve the network topology automatically under the
multi-domain environments.

This extension can expand the usage of BGP-LS protocol to multi-domain;
enable the network operator to collect the connection relationship between
different domains and then calculate the overall network topology
automatically based on the information provided by BGP-LS protocol.



Best Regards.
