使用 L3 OVN 服务插件的路由器风味¶
在本章中，我们将提供如何使用用户自定义风味创建路由器的示例。
注意
以下示例引用了一个虚拟的用户自定义服务提供商，在实际情况下，必须将其替换为用户提供的代码。
将服务提供商添加到 neutron.conf。第二个提供商是第一个提供商的高可用性版本
[service_providers] service_provider = L3_ROUTER_NAT:user-defined:neutron.services.ovn_l3.service_providers.user_defined.UserDefined
重新启动 neutron 服务器并验证用户自定义提供商是否已加载
$ openstack network service provider list +---------------+-----------------+---------+ | Service Type | Name | Default | +---------------+-----------------+---------+ | L3_ROUTER_NAT | user-defined | False | | L3_ROUTER_NAT | ovn | True | +---------------+-----------------+---------+
为路由器风味创建服务配置文件
$ 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 | +-------------+--------------------------------------------------------------------+
创建路由器风味
$ 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 | 65df2587-c535-4c3a-af2f-86b2968a3191 | | name | user-defined-router-flavor | | service_profile_ids | [] | | service_type | L3_ROUTER_NAT | +---------------------+------------------------------------------------------+
将服务配置文件添加到路由器风味
$ openstack network flavor add profile user-defined-router-flavor a717c92c-63f7-47e8-9efb-6ad0d61c4875
创建指定用户自定义风味的路由器。请注意创建的路由器的 ha 特性

注意
OVN 路由器在 OVN/OVS 级别原生支持高可用性，通过 BFD 监控实现。Neutron 不会参与高可用性方面的工作，超出路由器调度范围。因此，ha 属性与默认 OVN 风味的路由器相关联，并且始终设置为 True。这是为了与用户自定义风味路由器保持一致，对于用户自定义风味路由器，ha 属性将根据路由器的特性设置为 True 或 False。
