Best Linux (or BSD) hosted BGP?

Lots of replies saying which of BIRD/exabgp/frr/quagga/openbgpd folks prefer, but they're all pretty 
good. Honestly for such a project they're all just as great, it comes down mostly to what you're 
used to config-wise. Used to big metal router configuration? You might find BIRD foreign. Used to 
more functional code stuff? BIRD is pretty great. Others I have less experience with.

As for "something better than cobbling it together", I'd recommend just do that. Install your usual 
Linux/BSD distro, install one of the BGP daemons, and run a flow logger (eg pmacctd, which can split 
out flowspec which you can consume with whatever you're comfortable with). Setting up everything 
short of the actual flowspec inspection should be a half-hour endeavor, maybe three hours if you 
have to fight with the VM provider to get BGP filters working right :).
