1 M-LAG组网VLAN双活网关单挂场景配置举例（IPv4+IPv6）

1.1  组网需求

如图1-1所示，Device A和Device B组成M-LAG VLAN双活网关，单台M-LAG设备故障时另一台M-LAG设备仍可正常转发业务流量。在M-LAG VLAN双活网关中：

·     Device D通过M-LAG接口双归接入M-LAG系统中的Device A和Device B，并通过OSPF/OSPFv3动态路由与M-LAG系统实现路由互通。

·     Device F通过非M-LAG接口单归接入M-LAG系统中的Device A，并通过OSPF/OSPFv3动态路由与M-LAG系统实现路由互通。

1.2  适用设备及使用版本

 

设备	软件版本

Interface3	GigabitEthernet1/0/3
Interface4	GigabitEthernet1/0/4
Interface5	GigabitEthernet1/0/5
Interface6	GigabitEthernet1/0/6

 

1.4  配置限制和指导

对于非M-LAG接口单归接入的场景，为了使VLAN内的ARP/ND表项正常在两台M-LAG设备间同步，当本端M-LAG设备上行链路故障时，业务流量可以通过peer-link链路绕行到对端M-LAG设备上进行处理。请选择以下方式之一配置：

·     在两台M-LAG设备上将单挂业务VLAN配置为额外VLAN。（本例中采用这种方式，此方式要求设备上至少要有一个M-LAG聚合口，可以是空M-LAG聚合口或者设备上已存在的其他M-LAG聚合口）

·     在两台M-LAG设备创建一个空M-LAG聚合接口（无需加入任何物理接口），并将该M-LAG聚合接口加入单挂业务的VLAN。

建议在M-LAG设备上的单挂业务VLAN接口下配置ipv6 nd unsolicited-na-learning enable命令从未经请求的NA报文中学习邻居信息的功能。
