Open Stack

  Br-ex is meant for external network.
You can add br-ex to any interface which will allow reaching internet.
Br-int which your vms are already using is for internal network.

What do you mean by external interface? I access and get internet through
eth0 on my host.
So does that mean I will use eth0?

Just want to be sure cause some documents say I should add my private
interface(eth1) to br-ex

Thank you!

hello jake,

Can't see that you have added any external interface to br-ex in ovs-vsctl
show command output.

ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex <external interface>
ip link set up br-ex

Hi all! I have finally made some progress on networking, but now I have an
issue with accessing the internet from an instance.

After creating an instance, it receives a private IP from DHCP services
(including DNS servers) which I can see in the console. Trying to ping
yahoo.com does not work but I can ping 10.0.0.1 which is the private
network gateway.

I attached some helpful screenshots. I did notice that in the Network
Topology view, there is no gateway IP address for the Public network
showing,
But I did set the gateway to 192.168.100.98

Thank you in advance.
Jake
