<p class="MsoNormal">Secondly, I'd recommend putting an explicit preference on your entries, it's just better for everyone, and you don't get a credit back from Cisco for saving on a few ascii characters by implicitly using the default. Plus, if the default
is 0, which it is, then your next preference should be technically 1. But then having nothing and 1 seems silly, because if pref 1 is actually pref 2, then well, might as well call them pref nothing and pref 8. I digress.<u></u><u></u></p>
