Transit provider selection and peering strategy

Dr Peering -

We are looking to start peering.  Does transit provider selection have any impact on our peering strategy?

In some cases, selecting the right upstream transit provider can increase your chances of obtaining peering. From “The Art of Peering: Tactic #5...”

Let’s assume that you buy transit from a Tier 1 ISP (Global Crossing (GLBX) in this example).  As a Tier 1 ISP, Global Crossing by definition has access to the entire region through its peering sessions with the other Tier 1 ISPs.

Let’s further assume that GBLX has a less restrictive peering policy than the other Tier 1 ISPs and peers with ISP B, a large regional ISP that you wish to peer with.
