a policy leaking level 2 routes into level 1
a policy setting the attached bit on level 2 routes
a policy setting the attached bit on level 1 routes

Since R3 has L1 adjacency, it needs attached bit set to created default route towards L2 adjacency routers. However, since R3 is ignoring the attached bit, R1 and R4 has to leak L2 routes into L1 so R3 can learn about the outside networks.
