It can help in several ways: 1) If you proxy aggregate you put in a route object for the aggregate. This infiormation can be used to track down the cause of problems caused by proxy aggregation. 2) The route object can also contain information about "holes" in an aggregate, which can be quite useful when evaluating aggregation strategies. 3) The routing registry also contains 'aut-num' objects describing the routing policy of each AS: who they peer with, which routes they announce and accept. Given this information the consequences of proxy aggragation can be evaluated/simulated before putting a proxy aggregation in place. Daniel
