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?
