    "abstract": "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.",
