Creates a router in centralized mode.
In centralized mode, routing is configured only on the border leaf pairs.
When you create a router, the default mode is centralized. You can create a router with or without the --centralized option and achieve the same result.
Note
EFA does not support routers configured in distributed mode, although the feature was supported in a previous release. The functionality to configure distributed mode is turned off.Each of these examples creates 1 centralized router called R2.
$ openstack router create R2 $ openstack router create R2 --centralized
