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 inter Autonomous (inter-AS) Traffic
   Engineering (TE) related 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.
