That seems unlikely to be a good idea.

IIRC, bgpd is entirely single-threaded. It should be trivial to bind it to a single core using taskset on Linux (or the equivalent, on another OS). You can do this while it's running, or you can start it that way - modify the rc file that starts quagga & bgpd (or whatever you're using to get it started on boot).
