Basically the larger the ospf database, the longer it takes to do dijkstra. It's not a hugely complicated algorithm and most cpu's can handle fairly large calculations quickly. The challenge with putting everything into a single area is each time something flaps, the algorithm will be run. This can cause issues depending on the model of router and what is running on it - especially if there are lsa's for unstable links in the db.
Are you planning on putting customer routes into ospf? how are you planning on passing customer's vpn routing information - bgp?? > If we do summarization at ABR, MPLS cannot work since this is a continuous > MPLS domain. How would this stop MPLS from working?
