IRF组网目标验证和测试
查看HX设备IRF状态
查看ChuKou-R设备IRF状态
查看HX设备的ospf路由表并进行ping测试
Tips：
命令释义：ping -c 2 -a 172.16.10.254 172.16.11.254
-c 2：
指发送icmp报文的数量为2
-a 172.16.10.254 172.16.11.254：
指携带源地址172.16.10.254发送icmp至目标主机172.16.11.254
查看FenZhi01设备的ospf路由表并进行ping测试
查看FenZhi02设备的ospf路由表并进行ping测试
总结
盒式设备与框式设备配置IRF略有差异，但是IRF配置逻辑是相同的。
