I would say the quality of the physical link between R1 and R2 has nothing
to do with the problem, for these reasons:
1) You are not reporting any adjacency problems between R1 and R2. If it is
a matter of dropped LSA, the hellos would have trouble getting through too.
2) The external LSAs received by R2 need to be refreshed only once every 30
minutes. At the rate of once every 3 seconds, your routes could not be aging
out because of missed LSAs.
Do a "debug ip routing" to see the reason why IOS is removing those routes
from the RT.
