Yeahhh... It's by choice-- there are (old/outdated) static prefix filters on Zayo's peering session to the Gigapop. With the addition of MICE to AS57-- there's a lot more diverse traffic headed that direction than there used to be. I'll start a dialog with my contacts over there and see if we can get them to take more of a standard "transit" approach to that session. We have the same problem with our (relatively new) IPv4 prefix...MICE out...Level3/XO return... ~Matthew On Aug 31, 2011, at 3:28 PM, Jeremy Lumby wrote:
I have a case where I am seeing 199.199.0.0/16 in BGP via MICE/Northern Lights GigaPoP. I have noticed that traffic to this network takes MICE, however the return traffic is coming in across one of my public Internet connections. I am assuming that either by choice, or by accident that they are not accepting my route via MICE/Northern Lights GigaPoP. I am wondering who would be the best person to chat with about this since MICE does not list a peering contact for Northern Lights GigaPoP in the participants page, and I realize that the correct peering contact might be another level or two deeper.
Thanks, Jeremy
