Regarding the aggregation/deaggregation mess. This is due to the fact that ARIN is rather strict with IP assignements and how we route internally. Because ARIN wants us to use 80% of our ip blocks, before we can request new assignments from them we have to dole out addresses in /22's to each city we have, in order to use them up appropriately. Its been a bit of a nightmare trying to meet ARIN's policies and also try to meet the Internet Communities policies. Believe me, I would much rather advertise a /16 prefix out to the Internet, rather then a /22. We have not been able to accommodate this unfortunately.
Err... Why do you say you need to advertise a /22 for each city rather than the /16 for your entire network? What's inside your network and how you distribute your addresses there is not of concern for anyone outside of your network. Why don't you advertise the /16 via BGP and then let the IGP handle the /22 distribution to each city? -- Andre
