Creating a L3 OVN router with a user-defined flavor¶
In this section we describe the steps necessary to create a router with a user defined flavor.
Note
The following example refers to a dummy user-defined service provider, which in a real situation must be replaced with user provided code.
Add the service provider to neutron.conf:
[service_providers] service_provider = L3_ROUTER_NAT:user-defined:neutron.services.ovn_l3.service_providers.user_defined.UserDefined
Re-start the neutron server and verify the user-defined provider has been loaded:
$ openstack network service provider list +---------------+--------------+---------+ | Service Type | Name | Default | +---------------+--------------+---------+ | L3_ROUTER_NAT | user-defined | False | | L3_ROUTER_NAT | ovn | True | +---------------+--------------+---------+
Create a service profile for the router flavor:
$ openstack network flavor profile create --description "User-defined router flavor profile" --enable --driver neutron.services.ovn_l3.service_providers.user_defined.UserDefined +-------------+--------------------------------------------------------------------+ | Field | Value | +-------------+--------------------------------------------------------------------+ | description | User-defined router flavor profile | | driver | neutron.services.ovn_l3.service_providers.user_defined.UserDefined | | enabled | True | | id | a717c92c-63f7-47e8-9efb-6ad0d61c4875 | | meta_info | | | project_id | None | +-------------+--------------------------------------------------------------------+
Create the router flavor:
$ openstack network flavor create --service-type L3_ROUTER_NAT --description "User-defined flavor for routers in the L3 OVN plugin" user-defined-router-flavor +---------------------+------------------------------------------------------+ | Field | Value | +---------------------+------------------------------------------------------+ | description | User-defined flavor for routers in the L3 OVN plugin | | enabled | True | | id | e47c1c5c-629b-4c48-b49a-78abe6ac7696 | | name | user-defined-router-flavor | | service_profile_ids | [] | | service_type | L3_ROUTER_NAT | +---------------------+------------------------------------------------------+
Add service profile to router flavor:
$ openstack network flavor add profile user-defined-router-flavor a717c92c-63f7-47e8-9efb-6ad0d61c4875
Create router specifying user-defined flavor:
$ openstack router create router-of-user-defined-flavor --external-gateway public --flavor-id e47c1c5c-629b-4c48-b49a-78abe6ac7696 --max-width 100 +-------------------------+------------------------------------------------------------------------+ | Field | Value | +-------------------------+------------------------------------------------------------------------+ | admin_state_up | UP | | availability_zone_hints | | | availability_zones | | | created_at | 2023-05-25T22:34:16Z | | description | | | enable_ndp_proxy | None | | external_gateway_info | {"network_id": "ba485dc9-2459-41c1-9d4f-71914a7fba2a", | | | "external_fixed_ips": [{"subnet_id": | | | "2e3adb94-c544-4916-a9fb-27a9dea21820", "ip_address": "172.24.8.69"}, | | | {"subnet_id": "996ed143-917b-4783-8349-03c6a6d9603e", "ip_address": | | | "2001:db8::261"}], "enable_snat": true} | | flavor_id | e47c1c5c-629b-4c48-b49a-78abe6ac7696 | | id | 9f5fec56-1829-4bad-abe5-7b4221649c8e | | name | router-of-user-defined-flavor | | project_id | b807321af03f44dc808ff06bbc845804 | | revision_number | 3 | | routes | | | status | ACTIVE | | tags | | | tenant_id | b807321af03f44dc808ff06bbc845804 | | updated_at | 2023-05-25T22:34:16Z | +-------------------------+------------------------------------------------------------------------+
Create an OVN flavor router to verify they co-exist with the user-defined flavor:
$ openstack router create ovn-flavor-router --external-gateway public --max-width 100 +-------------------------+------------------------------------------------------------------------+ | Field | Value | +-------------------------+------------------------------------------------------------------------+ | admin_state_up | UP | | availability_zone_hints | | | availability_zones | | | created_at | 2023-05-25T23:34:20Z | | description | | | enable_ndp_proxy | None | | external_gateway_info | {"network_id": "ba485dc9-2459-41c1-9d4f-71914a7fba2a", | | | "external_fixed_ips": [{"subnet_id": | | | "2e3adb94-c544-4916-a9fb-27a9dea21820", "ip_address": "172.24.8.195"}, | | | {"subnet_id": "996ed143-917b-4783-8349-03c6a6d9603e", "ip_address": | | | "2001:db8::263"}], "enable_snat": true} | | flavor_id | None | | id | 21889ed3-b8df-4b0e-9a64-92ba9fab655d | | name | ovn-flavor-router | | project_id | b807321af03f44dc808ff06bbc845804 | | revision_number | 3 | | routes | | | status | ACTIVE | | tags | | | tenant_id | e6d6b109d16b4e5e857a10034f4ba558 | | updated_at | 2023-07-20T23:34:21Z | +-------------------------+------------------------------------------------------------------------+
List routers to verify:
$ openstack router list +--------------------------------------+-------------------------------+--------+-------+----------------------------------+ | ID | Name | Status | State | Project | +--------------------------------------+-------------------------------+--------+-------+----------------------------------+ | 21889ed3-b8df-4b0e-9a64-92ba9fab655d | ovn-flavor-router | ACTIVE | UP | b807321af03f44dc808ff06bbc845804 | | 9f5fec56-1829-4bad-abe5-7b4221649c8e | router-of-user-defined-flavor | ACTIVE | UP | b807321af03f44dc808ff06bbc845804 | | e9f25566-ff73-4a76-aeb4-969c819f9c47 | router1 | ACTIVE | UP | 1bf97e3957654c0182a48727d619e00f | +--------------------------------------+-------------------------------+--------+-------+----------------------------------+
