IRF组网拓扑图

IRF组网地址规划

IRF组网目标

HX_1和HX_2组成IRF设备，其中HX_1为主设备；

R_1和R_2组成IRF设备，其中R_1为主设备；

HX、FenZhi01和FenZhi02设备之间的业务地址段实现相互通信；

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。
