Network configuration
Before we start configuring tunnels and routing we first need to make sure the network of the machine you wish to configure as a CRXN router is configured correctly.
Assigning addresses and a subnet

Enabling forwarding
We will be setting up the machine that runs bird as a router so therefore we need to make your Linux kernel's network stack not drop IPv6 packets that it receives (addressed to it via Ethernet) but are not addressed to it via IPv6 address - in other words it must try do something with these packets, namely attempt to forward them one hop closer to their initial destination.
Enabling forwarding on all interfaces can be achieved as follows (you will need to be root):
echo 1 > /proc/sys/net/ipv6/conf/all/forwarding
However, after reboot it won't be saved and will go back to its defaults. Therefore
what you need to do is to enable forwarding on boot-up, this can be done by
adding an additional line to your /etc/sysctl.conf (which holds a bunch of
these statements), it should look like this:
net.ipv6.conf.all.forwarding=1
TODO: Weird experience with me, only doing all made it work
