The above should give you a good idea of inbound paths, and how diverse or common they are. Finally once you have narrowed down your search I would then ask the provider for an outbound trace to certain networks. Without bound traffic this is slightly different again depending if your taking full routes / partial or a default route, you might let BGP do its thing, or you might create route maps for each provider or use software to optimize outbound routes.<u></u><u></u></p>

<p><u></u> <u></u></p><p>We're looking at adding a second transit provider for redundancy (and hopefully more-or-less even load balancing). I was wondering what transit providers people would recommend pairing together to get the most diverse set of routes. Obviously you don't want your two upstreams to have very similar routes and paths.<u></u><u></u></p>
<p><u></u> <u></u></p><p>As a start I was thinking perhaps a Gang of Four provider plus a non-Go4 provider would make a good pairing but I'd really appreciate the comments of some of the more experienced BGP gurus on the list.<u></u><u></u></p>
