H3C DRNI配置

1. DRNI系统配置

    drni role priority 1              //值越小优先级越高，优先级高的为主设备
    drni system-mac xxxx-xxxx-xxxx    //DR设备的系统MAC地址必须相同，配置主交换机的桥MAC，通过disp device manuinfo查看
    drni system-number 1              //DR 系统中不同 DR 设备的系统编号必须不同
    drni system-priority 123          //DR 系统中所有 DR 设备的系统优先级必须相同
    drni restore-delay 180  //配置延迟恢复时间，从设备加入DR系统时进行 MAC 地址表项等信息同步的最大时间
   

2. Keepalive链路配置

   interface Ten-GigabitEthernet1/0/51
    port link-mode route
    combo enable fiber
    ip address 1.1.1.1 255.255.255.252
    
    drni keepalive ip destination 1.1.1.2 source 1.1.1.1 
    drni mad exclude interface Ten-GigabitEthernet1/0/51  //配置Keepalive链路接口为保留接口
   

3. Peer-link配置（IPL）

   # 配置聚合
   interface Bridge-Aggregation100
    link-aggregation mode dynamic
    port m-lag peer-link 1
   
   # 将接口加入聚合组
   interface Ten-GigabitEthernet1/0/50
    port link-mode bridge
    combo enable fiber
    port link-aggregation group 100
    
   # 配置聚合接口放通业务vlan
   interface Bridge-Aggregation100
    port link-type trunk
    undo port trunk permit vlan 1
    port trunk permit vlan 2 to 4094
    
   

4. 业务接口配置

   interface Bridge-Aggregation1
    link-aggregation mode dynamic
    port drni group 1
    
   interface GigabitEthernet1/0/1
    port link-mode bridge
    combo enable fiber
    port link-aggregation group 1
