You might want full routes for the ability to actually choose best path, and then the upstream providers loose control over what you are sending where. A and B can both filter what the customer sends to them based on network, and then the problem is solved. Unfortunately, this does not always give customers the flexibility they are looking for. I'm sure you know exactly what you are doing, but not every Joe that a provider takes on does. My point is only that this is a situation that I would not want to bring upon myself. --- -=<:gEm:>=- -<sMp>-<sMp>-<sMp>-<sMp>-<sMp>-<sMp>-<sMp>-<sMp>-<sMp>-- Gordon Mercer -=<Dedicated>=- [digitalNATION] 703 642 2800 -=<Servers>=- firstname.lastname@example.org <::>=-=<::>=--=<::>=-=<::>=--=<::>=-=<::>=--=<::>=-=<::>
