Scenario:
1. Create Router
2. Set gateway to external network
3. Create network with subnets 11.0.0.0/24 and 111.0.0.0/24
4. Create another network with subnet 12.0.0.0/24
5. Plug networks into the router
6. Start VM on any of the networks, check that VM acquired IP and ping to 8.8.8.8 works
7. Check where L3 agent is running by command 'neutron agent-list'
8. Verify network configuration: (L3 agent is running on node-1)

9. Ask pacemaker to disable-enable L3 agent:
pcs resource disable p_neutron-l3-agent
wait until it is stopped and then:
pcs resource enable p_neutron-l3-agent
10. L3-agent is moved to other controller (say to node-2)
11. Verify network configuration:
