You can use public tools to view bgp routing information from different viewpoints on the internet. A good starting point is to check out routeviews.org, jump on a box and 'show ip route' for a prefix you know the enterprise is advertising. That will show you a bunch of paths that are known to get to the enterprise customer, via different service providers.
Does that sound like what you are looking for?
