Does R2 have 0.0.0.0 in its routing table? If it does do you see the 0.0.0.0
in ISIS level-2 database when look on R1?
I can not try it right now, but I think as long as R2 has 0.0.0.0 you shall be
all set. Reason R3 gets 0.0.0.0 route is a connected bit it sees in LSA.
If you want to generate 0.0.0.0 into L2 from the router which does not have
default itself you need to have route-map on it.

As well running ISIS over partial mesh goes against ISIS design principle,
(unlike all other protocols it does not have natural way to deal with it), so
whatever way you try to do it you are in fixing things which designed to break.
