Hold that thought for a bit, and remember that at least *some* of us were
discussing whether to drop packets if we *DONT* have a route to the source.

=========> you cant if its a valid internet address...can you?

And the point is, that even *WITH* an assymetric route, that if I *DONT*
have a route back to you *somehow*,  it's probably time for me to toss the
packet out the window.  There's a distinction between "the route to the
source goes out an interface other than the one the packet arrived on"
and "there is no route to the source at all, via any interface".

routers may not have every router running bgp, so what do u do for such
scenarios..u default route it to a  bgp router....im missing your point.....
