This document describes a practical routing design that can be used in a large-scale data center (DC) design. Such data centers, also known as "hyper-scale" or "warehouse-scale" data centers, have a unique attribute of supporting over a hundred thousand servers. In order to accommodate networks of this scale, operators are revisiting networking designs and platforms to address this need.

            Use of BGP for Routing in Large-Scale Data Centers


   Some network operators build and operate data centers that support    over one hundred thousand servers.  In this document, such data    centers are referred to as "large-scale" to differentiate them from    smaller infrastructures.  Environments of this scale have a unique    set of network requirements with an emphasis on operational    simplicity and network stability.  This document summarizes    operational experience in designing and operating large-scale data    centers using BGP as the only routing protocol.  The intent is to    report on a proven and stable routing design that could be leveraged    by others in the industry.
