hi  ;
do u need the 3 routers to be in the same subnet ?? if so ...gateway of last resort will not work since there is a more specific route directly connected  , i guess u have to check then something like policy routing .
 
as u didnt mention that it is a must to put the routers in the same subnet , then creating two different subnets ( one between r1 subif1 and r2  and the second between r1subif2 and r3 ) will  simply solve your problem

Hence ruling out any static frame mapping or arp type solutions as these
are all layer 2 to layer 3 mapping techniques.


Couldn't you use, on the edges (r2/r3), a gateway of last resort like (ip
route 0.0.0.0 0.0.0.0 s0) so when you couldn't find a route it would send it
out s0 to the frame switch and then r1 would be able to pass it to the other
end...?

Another thought. The lab says that it doesn't want you to use layer 3 to
layer 2 mapping. Why can't you use static if it's, as you said, layer 2 to
layer 3?

These are just some thoughts, hope I spark something...
