几个难点：

1、题目要求了几种路由协议共存，又要保障路由连通，所以要设置eigrp和ospf在R2上的双向重分发（这些貌似不是CCNA要求范围吧！！我理解复杂了？？）。EIGRP上重分发OSPF协议的命令要用 redistribute ospf 10 metric 1544 20000 255 1 1500定义eigrp需求的5个参数，而不能直接用redistribute ospf 10来达到目的；OSPF协议上重分发EIGRP则可直接用redistribute eigrp 20 subnets来完成。

2、题目要求的扩展ACL要设置在R2的S0/1口的in方向，而不能直接设置在R4上，因为ACL并不能过滤路由器本身产生的数据流。
