Configuring Bird2

We now need to configure the routing daemon for your router which will allow you to exchange routes with other routers over the tunnels you will setup later. This is at the core of what makes CRXN an inter-network.

The software we use for this procedure is known as BIRD or BIRD Internet Routing Daemon, of which there are two versions:

1. Bird 1.6
2. Bird 2

You can use Bird 1.6 but you are on your own then in terms of configuration, the syntax differs slightly but we recommend (and for the rest of this document we will be) using Bird 2 as it comes with many bug fixes and improvements and most distributions (including Debian) now have support for it.

Installation

In order to install the BIRD daemon on your machine you should look for a package named bird2 or something similar (some repositories name it slightly differently - such as just bird). On a Debian-based system you can use:

sudo apt install bird2 -y

You can confirm that the version of BIRD you installed is version 2 with the command bird -v.
