Just a note, but this is an impractical solution. Consider that you had
65k routes on R4. That would be a lot of static routes to enter :)
Obviously the sealable solution in any AS where non BGP speakers exist is
the strategic use of default routing. A default route on R2 pointed at R3
would serve just a well. This could be done statically or injected into
the IGP via BGP.
