1、搭建拓扑，如上图所示，四台5呖分甾胗820交换机，用万兆口做IRF2MEM1 配置：irf member 1 priority 32#irf-port 1/1 port group interface Ten-GigabitEthernet1/0/49port group interface Ten-GigabitEthernet1/0/50#irf-port 1/2 port group interface Ten-GigabitEthernet1/0/51 port group interface Ten-GigabitEthernet1/0/52#save之后敲上irf-port-configuration active接口
3、MEM3配置：irf member 3 priority 28#irf-port 3/1 port group interface Ten-GigabitEthernet3/0/49 port group interface Ten-GigabitEthernet3/0/50#irf-port 3/2 port group interface Ten-GigabitEthernet3/0/51 port group interface Ten-GigabitEthernet3/0/52#save之后敲上irf-port-configuration active接口
