I deploy mirantis 7.0 and use GRE-type to build an OpenStack Now, I have to add an another external network to my OpenStack I follow this guide ( ( but it doesn't work :-(

First I create a bridge "br-gw" by "ovs-vsctl add-br br-gw"

And I add eth2 into my bridge by "ovs-vsctl add-port br-gw eth2"

I also let "external_network_bridge =" be empty in my l3_agent.ini and I set "bridge_mapping = phynet1:br-floating,phynet2:br-gw"and "network_vlan_ranges =external1,external2"in my ml2_conf.ini

But it doesn't work at all.

So, how can I add another external into my Mirantis openstack 7.0 ??

thanks a lot

To have several external networks with one L3 router is possible (no matter of tool used for deployment ) via external network provider
Working via dashboard won't help you would have to invoke Neutron CLI.

I think you are trying to add second external network to expend your floating IPs.

In that case, you can create new network from Admin > System > Network steps. But the new subnet of ip or network must be routed your public switch.

After you have created your external network you must also create router to route your private network to new external network. I also suggest to create new private network.

Project > Routers > Create Router and chose new external network as routers external network.

So, you do not need to create new bridge with OVS. If you have created new bridge your system may fail.
