Anyway, do you aggregate the customers to the single box, or do not, 2
level hierarchy scheme (backbone + AREA for big nodes) is quite
satisfacted.
Another problem - how do you flood small updates. For example, if we here
allocate dial-up addresses from the central cache, amd I inject this host
addresses into the network. Through, both methods (OSPF or IBGP) works
fine for the middle-size dialup pop's, and I don't think you need to do
it instead of using local address-pools in case of large dialup pop's.
