[NANOG] Re: question about peering relationships

It would likely be common with Hurricane Electric as a peer. They peer freely and their good value means they're in 
many BGP mixes.

Subject: [NANOG] question about peering relationships

Does the following ever happen in reality? Do you think it is strange and unlikely?

The lateral (i.e., non-transit) peer of an AS is also the transit provider of the AS's transit provider.  Example: AS A 
has AS B as a transit provider and AS C as a lateral peer, and AS C is a transit provider of AS B.

Thank you.

Sriram
