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.
$ openstack router create router +-----------------------+--------------------------------------+ | Field | Value | +-----------------------+--------------------------------------+ | admin_state_up | UP | | description | | | external_gateway_info | null | | headers | | | id | 24addfcd-5506-405d-a59f-003644c3d16a | | name | router | | project_id | b1ebf33664df402693f729090cfab861 | | routes | | | status | ACTIVE | +-----------------------+--------------------------------------+
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.
_uuid : 1c2e340d-dac9-496b-9e86-1065f9dab752 default_gw : [] enabled : [] external_ids : {"neutron:router_name"="router"} name : "neutron-a24fd760-1a99-4eec-9f02-24bb284ff708" ports : [] static_routes : []
The OVN northbound service translates this object into logical flows and datapath bindings in the OVN southbound 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.

Add the logical port to logical switch.

Add the logical router port to the logical router object.

The OVN northbound service translates these objects into logical flows, datapath bindings, and the appropriate multicast groups in the OVN southbound database.

In addition, if the self-service network contains ports with IP addresses (typically instances or DHCP servers), OVN creates a logical flow for each port, similar to the following example.
Datapath: 4a7485c6-a1ef-46a5-b57c-5ddb6ac15aaa Pipeline: ingress table= 5( lr_in_arp_resolve), priority= 100, match=(outport == "lrp-f112b99a-8ccc-4c52-8733-7593fa0966ea" && reg0 == 192.168.1.11), action=(eth.dst = fa:16:3e:b6:91:70; next;)
On each compute node, the OVN controller service creates patch ports, similar to the following example.
7(patch-f112b99a-): addr:4e:01:91:2a:73:66 config: 0 state: 0 speed: 0 Mbps now, 0 Mbps max 8(patch-lrp-f112b): addr:be:9d:7b:31:bb:87 config: 0 state: 0 speed: 0 Mbps now, 0 Mbps max
On all compute nodes, the OVN controller service creates the following additional flows:
