2018-08-29 Update: This tutorial is now very out of date. The Yggdrasil team now maintains great installation guides here. At Philly Mesh, we like to play around with pieces of technology that aren’t directly related to our core software stack. One such piece of software is Yggdrasil, an encrypted IPv6 networking implementation developed by Arceliar. Yggdrasil borrows many ideas from cjdns, but was primarily written to test a new routing scheme developed by Arceliar.

I have opted to install a GUI package to allow for easier configuration (though I also wanted to see what it had to offer over editing configuration files). The package used here is luci-app-cjdns, relying on the LuCI interface that comes default in most OpenWRT images.
