实验二策略的使用

需求：1、R3到192.168.1.1 192.168.3.1的路由走R3-R2-R1，并留有备份
2、R3到192.168.2.1 192.168.4.1的路由走R3-R4-R1，并留有备份
3、10.0.12.0、10.0.14.0的路由不引进ospf中
在左侧起rip,右边起ospf在R2,R4的两边分别起RIP和ospf
将rip发不到ospf中

1、匹配192.168.1.0 192.168.3.0的路由将走R2的cost改为20，走R4的cost改为30


2、匹配192.168.2.0 192.168.4.0的路由将走R2的cost改为30，走R4的cost改为20

3、10.0.12.0、10.0.14.0的路由不引进ospf中
使用前缀列表匹配这两个网段
