Routers¶

Routers pass traffic between layer-3 networks.

Note

Currently, OVN lacks support for routing between self-service (private) and provider networks. However, it supports routing between self-service networks.

Create a router¶

On the controller node, source the credentials for a regular (non-privileged) project. The following example uses the demo project.

On the controller node, create router in the Networking service.

$ openstack router create router

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          : []

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-v4 to the router router.
```
$ openstack router add subnet router selfservice-v4
```
Note

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.

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,

           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:

cookie=0x0, duration=6.667s, table=0, n_packets=0, n_bytes=0,
    idle_age=6, priority=100,in_port=8
