Hi Yi,
I think this is mentioned in Documentation/faq/issues.rst,
see
Q: I created a tap device tap0, configured an IP address on it, and added it to
a bridge, like this::
$ tunctl -t tap0
$ ip addr add 192.168.0.123/24 dev tap0
$ ip link set tap0 up
$ ovs-vsctl add-br br0
$ ovs-vsctl add-port br0 tap0
I expected that I could then use this IP address to contact other hosts on the
network, but it doesn't work. Why not?
...
Regards,
William
