Before you throw too many stones, these guys (I happen to know) take
transit from UUnet, and not, before you ask, over the MAE. Personally
I don't see a problem with this behaviour as a last resort.

If they buy transit, or do not buy transit from UUNet makes no difference.
You don't see a problem with pointing default at UUNet or any other
provider? This trace was to a network that did not exist, so it should not
have been sent to UUNet.

Ummm...correct me if I am wrong, but isn't transit usually defined as
being given explicit permission to send any and all traffic to the party
from whom transit is being bought? You mean ISP X who buys transit
from NSP Y can't point default at them? Why not? Isn't that what they are
paying for?

Or did you get confused and really mean that NSP X shouldn't be providing
transit over a public exchange point? As Alex pointed out, it was only as
a last resort that transit traffic would flow over the XP.


Ok, say I sell transit, say over a point to point 10 meg ethernet from my
POP to the customer. This customer may also be connected to MAE-East with
say a gigaswitch port. Just because I provide this customer a 10 meg
transit connection does NOT give them the right to point default to me at
MAE-East or any other NAP.

If it was OK for providers to do that, then I have a great new business.
Why not start a www farm and provide hosting for very good prices. We then
buy a T1 into any major NSP and get a gigaswitch connection at MAE-East.
So we are spending around 7K a month for access, now we just point default
to a NSP and we are set. Since you are a web farm, most of your data is
outgoing so for a little money you get a lot of bandwidth.

Am I the only one out there the thinks it is not ethical to point default
to a provider over a NAP without their permission? Just because someone
sells you transit does not give you the right to point default to them at
a NAP. Sure you can point default all day long over the connection you are
buying, but not over a NAP without their permission.
