Does anyone have any opinions as to whether one option is better than the other? Are there options that would be better than either of these? Are there serious risks to either option?
My sense is that either of these would be a fairly benign change, only having a marginal impact on routing efficiency in either case. It seems like the better option is the one that retains the greater number of routes within some margin of safety. What do you think?
I chose number 2. It works so well I'm starting to wonder why any network with less than, say, three or four transit providers would want to do anything else, even without system limits. My philosophy is rapidly becoming "Let the settlement-free club worry about all the deaggregated prefixes." Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---
