North South Networking via Single External Network¶
The following figure illustrates one typical networking mode, the north south networking traffic for the tenant will be centralized through single external network. Only one virtual router is needed even if the tenant’s network are located in multiple OpenStack regions.

How to create this network topology¶
The first step is to create the left topology, then enhance the topology to the right one. Different order to create this topology is also possible, for example, create router and tenant network first, then boot instance, set the router gateway, and associate floating IP as the last step.
Create external network ext-net1, which will be located in RegionTwo.
$ neutron --os-region-name=CentralRegion net-create --provider:network_type vlan --provider:physical_network extern --router:external --availability-zone-hint RegionTwo ext-net1
