拓扑图：

标记：接入层交换机我们标记为sw1,做热备的两台交换机，左边的我们标记为sw2，右边的标记为sw3。
说明：我这里的连线方式和拓扑上的不一样，具体方式如下：
Switch1 F0/1 <----> Switch2 F0/1
Switch1 F0/2 <----> Switch3 F0/2
Switch2 F0/10 <----> Switch3 F0/10
Switch2 F0/2 <----> Switch4 F0/2
Switch3 F0/1 <----> Switch4 F0/1
Router1 F0/0 <----> Switch4 F0/0

sw4我这里没有做任何配置，大家可以根据需要在上面作访问控制列表之类的配置，好了，配置过程中遇到了一些问题，不过最后都解决了，坚持就是胜利啊！
