Hi,

We have a use case where there are multiple user VRFs being leak routed
to and from tunnels that are on the core VRF. Traffic from user VRF to a
tunnel can be done the normal way by specifying the netdev directly on
the route entry on the user VRF route table:

ip route add <prefix> via <tunnel_end_point_addr> dev <tunnel_netdev>

But traffic received on the tunnel must be leak routed directly to the
respective a specific user VRF because multiple user VRFs can have
duplicate address spaces. I am thinking of using ip rule but when the
iif is an enslaved device, the rule doesn't get matched because the
ifindex in the skb is the master.

My question is: is this a bug, or is there anything else that can be
done to make sure that traffic from a tunnel being routed directly to a
user VRF? If it is the later, I can work on a patch.

Thank you,

Stephen.
