scapy (https://scapy.net/) is likely going to be your friend for that
type of research. I did my thesis on NAT64, so I assume you will have a
lot of fun coding that.

While we do a lot of things with bird, I am not sure why you'd need it
for your research, because it is mainly a control plane utility,
forwarding is still done in kernel.

Best regards,
