Those tools are not suitable for regression testing ( I know I wrote exabgp ) not saying they could not be adapted though.

Fizzing may return crashes or issues with the daemon but it is unlikely. You need predictable input for regression testing and in our particular case how do you detect a corruption without knowing what the behaviour of the router should be on that particular input.

If it was that simple vendors would have done it
