Abstract:
   Data centers have become critical components of the infrastructure
   used by network operators to provide services to their customers.
   Data centers are attached to the Internet or a backbone network by
   gateway routers.  One data center typically has more than one gateway
   for commercial, load balancing, and resiliency reasons.

   Segment routing is a popular protocol mechanism for operating within
   a data center, but also for steering traffic that flows between two
   data center sites.  In order that one data center site may load
   balance the traffic it sends to another data center site it needs to
   know the complete set of gateway routers at the remote data center,
   the points of connection from those gateways to the backbone network,
   and the connectivity across the backbone network.

   Segment routing may also be operated in other domains, such as access
   networks.  Those domains also need to be connected across backbone
   networks through gateways.

   This document defines a mechanism using the BGP Tunnel Encapsulation
   attribute to allow each gateway router to advertise the routes to the
   prefixes in the segment routing domains to which it provides access,
   and also to advertise on behalf of each other gateway to the same
   segment routing domain.
