this is getting far more complex than that point warrants. someone said one should not distribute bgp into igp and igp into bgp. i tried a simple example where o there are few non-default routes but they are significant o there are two routers that have external neighbors, at least one of which must be an ebgp speaker and the other may be bgp or default o and there is a third router *in the middle* to which a customer is attached the point is o the router in the middle *must* do dynamic routing, or there will be a routing loop o for many reasons, it is likely the middle router will be an igp, not bgp speaker o hence very careful redistribution of ebgp to igp, and of igp to bgp is useful randy
