Abstract:

   This document specifies the procedure for distributing Border Gateway
   Protocol-Link State (BGP-LS) key parameters for inter-domain links
   between two Autonomous Systems (ASes).  It defines a new type within
   the BGP-LS Network Layer Reachability Information (NLRI) for an
   Inter-AS Link, as well as three new type-length-values (TLVs) for the
   BGP-LS Inter-AS Link descriptor.  These BGP-LS extensions enable
   Software-Defined Networking (SDN) controllers to retrieve network
   topology across Inter-AS environments.

   These extensions and procedures allow network operators to collect
   inter-domain interconnect information and automatically compute the
   end-to-end network topology using information provided by the BGP-LS
   protocol.
