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.
Only Neutron and Tricircle Local Neutron Plugin are required to be deployed in RegionThree if you want to make the external network being floating and applicable to all tenant’s network.

Figure 1 North South Networking via Single External Network
Note
Please note that if local network and external network are located in the same region, attaching router interface to non local router will lead to one additional logical router for east-west networking. For example, in the following figure, external network ext-net1 is in RegionTwo, and if local network net2 is attached to the router R1, then the additional logical router R1 for east-west networking is created.

How to create this network topology¶
Following commands are executed to create the Figure 1 topology. 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 RegionThree.
