华为多级m-lag简单配置案例

需求分析：
1、配置设备组建M-LAG系统，配置服务器M-LAG双归接入IP网络。
2、配置Monitor Link关联上行接口和下行接口，避免因上行链路故障导致流量丢弃，使用命令timer recover-time配置回切时间，防止上行链路故障回切后因为路由没有收敛而导致丢包。
3、Leaf1A与Leaf1B之间组建M-LAG系统，Peer-Link接口为Eth-Trunk0，成员接口为各设备上的10 GE1/0/11与10GE1/0/12接口。
4、Leaf设备的网关规划连接VM1的物理口允许Vlan1300通过，连接VM2的物理口允许Vlan1301通过。
5、Spine1与Leaf1A、Leaf1B之间运行OSPF协议，所有接口均属于OSPF区域0（包括Loopback1接口），Spine1上Loopback1接口IP地址模拟服务器需要访问的外部地址。
