[j-nsp] routing problem

What you want to achieve is an altered routing table. If you don't want to
apply import policies maybe you can:

- apply an export policy to your iBGP neighbor changing the localpref for
the subnets. I don't know if this is technically possible on JunOS, and as
far as my understanding goes, localpref is transitive so maybe you should
not go this route (messing with you iBGP that is).

- add static routes on the hosts pointing to int1 and int2 for the subnets
behind that router. alternatively, add RIP routing on the hosts and send
two routes and two defaults from your routers.

I still think an import policy is the way to go, but maybe this helps you.
