L2 Mode

第2层模式是最容易配置的:在许多情况下,你不需要任何特定协议的配置,只需要IP地址。

第2层模式不需要将IP绑定到工作节点的网络接口。它通过直接响应本地网络上的ARP请求来工作,从而将机器的MAC地址提供给客户端。

为了对来自 IPAddressPool 的IP进行通告,必须将 L2AdvertisementIPAddressPool 相关联。

验证

搞个service测试一下(参考红帽:https://docs.redhat.com/zh_hans/documentation/openshift_container_platform/4.13/html/networking/metallb-configure-services)
