  • Using the intermediate ISP provider to carry the traffic by the two ISPs.
  • It is an extra burden to the two ISPs.
  • If hierarchy often peer with each other then reduces the cost for two ISPs to avoid intermediate ISP provider.

So, the t wo ISPs at the same level of the hierarchy often peer with each other.
