Public bug reported:
As shown below,the network that's internal vlan is 4 only has 'qr-' port
in compute2
[root@compute2 ~]# ovs-vsctl show|grep "tag: 4" -C 2
type: internal
Port "qr-1862e19a-91"
tag: 4
Interface "qr-1862e19a-91"
type: internal
[root@compute2 ~]#
I checked the network's flow tables on br-tun,they are right.
[root@compute2 ~]# ovs-ofctl dump-flows br-tun|grep "dl_vlan=4"
