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.
