OK that is good. That means we would only need one extra AS for the DC area. Carl, is UUnet going to provide us with backup to MAE-EAST and beyond if our new T3 would break? This sort of defines whether we have to split WTN/MAE-EAST and NPB/PennAve into two seperate ASes. If they do, we need a different (new) AS for WTN/MAE-EAST. If they do not, we can use 3920 for WTN/MAE-EAST as well.

The main thing why we would have to split into more ASes (just like why Tokyo and WTN should be in different ASes) is that whenever our links break, we have to travel though another AS to get to the other side. You cannot transit from one end of an AS to the other end of the same AS through some other AS. BGP simply cannot do this....

PS Also, since you have a transit agreement with UUnet now, getting another transit agreement with MCI makes things very complicated and can cause sub-optimal routing. We'll probably have to figure this out in January and see if it is really all that bad.
