Hi Yi
The flows in br-int are configured by ODL. OpenStack normally uses tags instead of flows to route the packets. However please check the service plugin set for L3 services in Neutron config file or process l3-agt on network node. L3 can be configured either to be handled by OpenStack or ODL. // Hemanth

Hi, All
I followed https://wiki.opendaylight.org/view/OpenStack_and_OpenDaylight to integrate Openstack and SFC. I saw br-int was created by ODL.

I'm not sure if Openstack neutron really connected to ODL.

When I ran neutron commands to create net, subnet, router, etc, neutron didn't report any error, but it seems openflow tables aren't changed after I created net, subnet, router and start a VM. Anybody knows how to check if neutron is working normally with ODL?
