Public bug reported:

Brief overview and reproducing steps:
1. Create tenant network, let's say 10.3.2.0/24.
2. Create centralized HA router. Attach it at 10.3.2.1
3. Boot VM and ping 10.3.2.1 - works.
4. Create distributed router. Attach it at any free IP, e.g. 10.3.2.5
5. Try to ping 10.3.2.1 from VM - fails. Ping 10.3.2.5 - works.

I can reproduce this consistently. The setup might be a bit of a corner case:
 - deployment with openstack kolla. Openvswitch.
 - openstack pike. neutron 11.0.2
 - tenant provider networks are vlan
 - there are 2 neutron nodes to host HA routers
 - all compute nodes configured for DVR

No errors in logs.
On the compute node hosting the VM, I can see dropped packages on integration bridge br-int.
