Hi Debbie,

Im assuming that you want to advertise longer AS paths out your least
preferred ISP. Would such a strategy reduce traffic or have the unintended
effect of completely stopping traffic from that ISP? Your customers' ISPs
may completely ignore the routes advertised with the longer AS. Perhaps its
a quality of service issue you have to arrange with the soon-to-be-retired
ISP.
