"We also had problems where transit customers said don't want to be
exported to a certain IX point of presence while he wanted to be
exported at a different location."

That's a fairly normal request. I think nearly every major IP transit
provider has built out a BGP action community system to allow their
customers to control prefix announcements in the way you're describing
it here (e.g. prepending and no-export to certain peers/upstreams). Of
course outbound traffic from your customer to "the rest of the world"
can not be controlled that way.

Best regards,

It's simply their police and some big companies do not have a policy which is the same for everyone peering, say, content provider X will peer with you if you reach >80Mbps, could not always be true. I have lived a situation where someone demanded to peer to a DC I happened to manage at that time because his competitor was peering as well and sharing the same IX, but my company had no real reason to peer from the NOC perspective and using another port would just be a waste of time and money with no real advantage other than a barely better latency. Manager said no thanks, as asked for our peering policy to become private. Sometimes things just don't have a better explanation and some people just don't want to accept a different policy to different players.

Who ever told him he could pick where we export who? Nobody. In the end if you are seriously interested to join the IX you will bet the full list for MLPEs, etc. Otherwise it's just the policy for the club.
