| 58 | 2.Floodlight intercepts packet, allocates IP and responds with an offer |
| 59 | 3.Client responds to offer by sending DHCP request |
| 60 | 4.Floodlight intercepts request, triggers migration event and DHCP acks |
| 61 | 5.Client receives DHCP ack, establishing L3 connectivity. Meanwhile, the network-level FL controller inserts flows at the root and gateway OVSBs and removes any existing flows belonging to the client. |
