Is there a better way to implement this use case? Seems that it's a
common one for VRFs.

I have a reproducer using namespaces attached in this email (gre_setup.sh).
A ping is initiated from h0:
ip netns exec h0 ping -c 1 11.0.0.2
As I have seen on our target platform, the iif is the VRF device. In
this case it is the core VRF. Thus, the ip rule with iif equals to the
GRE tunnel doesn't get hit.
This is I think is the relevant perf script output. All the outputs are
in the attached perf_script.txt.

The iif when the fib is being looked up is the vrf_r1c (6). There is
another error in the perf_script where the iif is the lo device and the
oif is vrf_r1c.
