Routers
Routers pass traffic between layer-3 networks.
Create a router
On the controller node, source the credentials for a regular (non-privileged) project. The following example uses the
demoproject.On the controller node, create router in the Networking service.

OVN operations
The OVN mechanism driver and OVN perform the following operations when creating a router.
The OVN mechanism driver translates the router into a logical router object in the OVN northbound database.

Attach a self-service network to the router
Self-service networks, particularly subnets, must interface with a router to enable connectivity with other self-service and provider networks.
On the controller node, add the self-service network subnet
selfservice-v4to the routerrouter.$ openstack router add subnet router selfservice-v4Note
This command provides no output.
OVN operations
The OVN mechanism driver and OVN perform the following operations when adding a subnet as an interface on a router.
The OVN mechanism driver translates the operation into logical objects and devices in the OVN northbound database and performs a series of operations on them.
Create a logical port.
