<p class="MsoNormal">I have a /24 that I would love to advertise as 2 /25’s, but the affects on everyone else is just too much. I take full routes from 4 providers, and I certainly don’t want to add over 100K. Carriers and enterprises have to pay a lot for
our edge routers doing bgp and most don’t want to upgrade. We would benefit from advertising /25’s but it hurt’s more than it helps.<o:p></o:p></p>
