# man ifconfig

fib fib_number
Specify interface FIB. A FIB fib_number is assigned to all
frames or packets received on that interface. The FIB is not
inherited, e.g., vlans or other sub-interfaces will use the
default FIB (0) irrespective of the parent interface's FIB. The
kernel needs to be tuned to support more than the default FIB
using the ROUTETABLES kernel configuration option, or the
net.fibs tunable.
tunnelfib fib_number
Specify tunnel FIB. A FIB fib_number is assigned to all packets
encapsulated by tunnel interface, e.g., gif(4), gre(4) and
vxlan(4).
[...]
When I force the interface gre0 into fib 3 as well,
then the IPv6 packages from inside the tunnel show up in fib 3 again.
Is there a possible mixup ?
