Routing Question:

If backbone providers A, B, and C are fully peering with one another and little guy X has no peering with A but does with B and C. Will packets still travel from X(customer) to A(customer) and back again?

Yes, via B or C. That is to say that it's sufficient to buy transit once, assuming the connectivity between A, B and C is working. Note that this isn't always the case. ;-( Tony
