When other networks make your > life easier, you benefit. This confirms my statement. You save nothing by deploying SAV on your network. There may be some indeterminate benefit at some indeterminate time in the future after everyone else in the world correctly implements SAV. But there is no way to verify if every other network in the world has correctly deployed SAV. Even if everyone deploys SAV/uRPF you never know when someone may misconfigure something, so you still have to keep doing everything you were doing. In the mean time, you get to pay for the extra costs for deploying SAV/uRPF in addition to doing everything you were already doing. http://www.rhyolite.com/anti-spam/you-might-be.html > If you want others to help you, help them. I've already done my part. I'm still waiting for others to help me. Should I be expecting a check in the mail?
