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
