1. ARP rules (not correct)
vagrant@compute:~/devstack$ sudo ovs-ofctl dump-flows -OOpenflow13 br-int | grep arp | grep 10.1.0.2
cookie=0x0, duration=2448.117s, table=20, n_packets=10, n_bytes=420, priority=1024,arp,tun_id=0x58,arp_tpa=10.1.0.2,arp_op=1 actions=move:NXM_OF_ETH_SRC[]>NXM_OF_ETH_DST[],set_field:fa:16:3e:df:5b:6f>eth_src,load:0x2->NXM_OF_ARP_OP[],move:NXM_NX_ARP_SHA[]>NXM_NX_ARP_THA[],move:NXM_OF_ARP_SPA[]>NXM_OF_ARP_TPA[],load:0xfa163edf5b6f->NXM_NX_ARP_SHA[],load:0xa010002->NXM_OF_ARP_SPA[],IN_PORT
RJ’s Note: fa:16:3e:df:5b:6f is private network DHCP server(not expected). fa:16:3e:f3:db:1f is tempest* network DHCP server (expected)
2. Tunnel id is correct
vagrant@compute:~/devstack$ sudo ovs-ofctl dump-ports-desc -OOpenflow13 br-int | grep tap
6(tap4cb434bf-ce): addr:fe:16:3e:3d:aa:7c
vagrant@compute:~/devstack$ sudo ovs-ofctl dump-flows -OOpenflow13 br-int | grep 'table=0.*port=6'
cookie=0x0, duration=3931.023s, table=0, n_packets=447, n_bytes=51743, in_port=6,dl_src=fa:16:3e:3d:aa:7c actions=set_field:0x58->tun_id,load:0x1->NXM_NX_REG0[],goto_table:20
3. Neutron net list
vagrant@control:~/tempest$ neutron net-list

4. DHCP namespace
vagrant@control:~/tempest$ sudo ip netns
qdhcp-53c2d45b-60c2-4874-b117-92569c47788a
qdhcp-b48192eb-93bc-46ec-ad70-0d1f7d3970a7
5. Tempest* DHCP MAC
vagrant@control:~/tempest$ sudo ip netns exec qdhcp-53c2d45b-60c2-4874-b117-92569c47788a ifconfig tap1b44b6bf-b5 | grep HWaddr
tap1b44b6bf-b5 Link encap:Ethernet HWaddr fa:16:3e:f3:db:1f
6. private DHCP MAC
vagrant@control:~/tempest$ sudo ip netns exec qdhcp-b48192eb-93bc-46ec-ad70-0d1f7d3970a7 ifconfig tap09bc0606-79 | grep HWaddr
tap09bc0606-79 Link encap:Ethernet HWaddr fa:16:3e:df:5b:6f
7. VM in tempest* cannot access to metada server:
$ sudo arp -d 10.1.0.2; ping -c 1 10.1.0.2; sudo arp; curl http://169.254.169.254
curl: (7) couldn't connect to host
8. VM in tempest* can access to metadata server after manually set ARP for DHCP server
$ sudo arp -d 10.1.0.2; sudo arp -s 10.1.0.2 fa:16:3e:f3:db:1f; curl http://169.254.169.254
