I have configured bird4 with the example config provided in the DN42 wiki (https://dn42.net/howto/Bird) (sorry about the HTML entities). The result is: Bird populates my routing table with all the correct routes, but spawns very huge amounts of BGP traffic. I ran it overnight accidentally, and it spawned over 70GB traffic on some interfaces, so these particular peers closed their VPN tunnels to me, which is understandable. I have created a minimal config by myself, which has the same result. However, peering with quagga works as expected, with all routes and little traffic.
Can you provide your configuration? Are you sure the large amount of traffic is BGP traffic, and not just a routing loop? You can try to log debug messages, see: http://bird.network.cz/?get_doc&f=bird-3.html#ss3.3 In your case, it's probably a good idea to use this in one of your BGP protocol: debug { packets }; (it may generate quite a lot of messages) Baptiste
