Title:
Using dvr and centralized routers in same network fails
Status in neutron:
Opinion
Bug description:
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, no-snat 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.
