I wrote an article about how to install the protocol in webOS.
Please see my blog https://yisooan.wordpress.com/2018/10/18/lg-webos-4-how-to-add-babel-routing-protocol-in-webos/
Not only Community Edition but also Open Source Edition can install and the article fits on both.
In addition, see https://en.wikipedia.org/wiki/Babel_(protocol) as well.
