1.24.3  M-LAG双活网关场景下通过动态路由接入M-LAG配置举例

1. 组网需求

如图1-19所示，用户在服务器上通过三层路由方式接入到M-LAG时，需要满足以下要求：

·     当一条接入链路发生故障时，流量可以快速切换到另一条链路，保证可靠性。

·     用户流量在两条接入链路上负载分担。

2. 组网图

图1-19 M-LAG双活网关场景下通过动态路由接入M-LAG配置组网图

‌

3. 配置限制和指导

配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下配置不冲突。

同级M-LAG设备的m-lag system-mac应配置为相同，不同级M-LAG设备的m-lag system-mac一定要配置为不同。

M-LAG双活网关组网环境下，M-LAG设备的下行VLAN接口不要配置本地代理ARP/ND功能，否则会触发流量环路。有关ARP/ND本地代理功能的详细介绍，请参见“三层技术-IP业务配置指导”中的“代理ARP”和“IPv6邻居发现”。
