            <p>Propane is a new language for configuring the network.
              It lets you write a single, high-level routing policy for
              your network. The Propane compiler can then generate a
              collection of legacy vendor configurations that are
              guaranteed to implement the policy correctly. The language
              and compiler provide the following features and guarantees:
            </p>
            <h3>Language and Compiler Guarantees</h3>
            <ul>
              <li>The language lets your write routing policy as if you alway have <b>centralized visibilty</b> of the network</li>
              &nbsp
              <li>The compiler performs <b>static analysis</b> of the routing policy to proactively find potential issues.</li>
              &nbsp
              <li>The Propane compiler generates a collection of configurations that run the
                <b>distributed</b> BGP routing protocol. There is no centralized coordination</li>
              &nbsp
              <li>The BGP configurations are guaranteed to correctly adapt to <b>all possible failures</b> so that
                the most preferred paths are always used when available.</li>
