How should I configure ovs so that it respects the system design?  
Should I add some flows?  
Do I have to set the type of some port in “patch” and connect it to other ports?  
How do I connect SF0 and SF1 to URL filter APP?  
My current ovs configuration:

```auto
ubuntu@localhost:~$ sudo ovs-vsctl show
d3a1e07e-43a0-45a8-bbc4-da75864bc5bc
    Bridge ovsbr2
        Port p0
            Interface p0
        Port ovsbr2
            Interface ovsbr2
                type: internal
        Port en3f0pf0sf5 -- SF1
            Interface en3f0pf0sf5
    Bridge ovsbr1
        Port pf0hpf
            Interface pf0hpf
        Port ovsbr1
            Interface ovsbr1
                type: internal
        Port en3f0pf0sf4 --SF0
            Interface en3f0pf0sf4 
    ovs_version: "2.15.1"

```

```auto
sudo ovs-appctl dpctl/dump-flows
recirc_id(0),in_port(2),eth(src=04:3f:72:f4:43:6a,dst=ff:ff:ff:ff:ff:ff),eth_type(0x0800),ipv4(frag=no), packets:4, bytes:1368, used:1.830s, actions:3

```

```auto
ubuntu@localhost:~$ sudo ovs-ofctl dump-flows ovsbr1
 cookie=0x0, duration=352795.033s, table=0, n_packets=293, n_bytes=25802, priority=0 actions=NORMAL
ubuntu@localhost:~$ sudo ovs-ofctl dump-flows ovsbr2
