Create a tunnel interface on R2 with R3's e0 ip address as destination
(and r2's e0 as source)

then run backup interface br0/0 on the tunnel If.

the tunnel would go down when R3's e0 would go down, triggering your
backup interface.

a wizard called Carlos Mendioroz came up with this some time ago so i
cannot take the accolade.
