I updated my example files. The flow for host 1 to host 1 end attempts to use MPLS and can be tested via ip netns exec h1 ping -c1000 172.16.100.3 and gets host unreachable. The flow for host 2 to host 2 end uses vlan 20 and can be tested via ip netns exec h2 ping -c1000 172.16.100.4 and works fine. Both should travel over a veth pair using the same flow between switches b4 and b5. I am not sure why the MPLS is not going over the veth pair
