Indeed.

I, for example, have an upstream that filters only on 
AS_PATH. Naturally, we are quite aggressive and insistent 
about filtering both on AS_PATH and prefix list across 
interconnects to our downstreams, but if things were to blow 
up on our side, the upstream in question would not be 
protected (unless, of course, they are relying on "max-
prefix" as well).

Mark.
