实验要求
1、按照图示配置 IP 地址，R1，R3，R4 上使用 loopback 口模拟业务网段
2、R1 和R2 运行 RIPv2，R2，R3和R4运行 oSPF，各自协议内部互通
3、在 RIP 和 oSPF 间配置双向路由引入，要求除 R4 上的业务网段以外，其他业务网段路由都引入到对方协议内部
4、使用路由过滤，使 R4 无法学习到 R1的业务网段路由，要求使用 prefix-list 进行匹配
5、0SPF 区域中不能出现 RIP 协议报文

路由过滤
因为需要R4上的业务网段不引入RIP协议网段中，所以在R2上配置路由过滤：
[R2]acl 2000
[R2-acl-basic-2000]rule permit source 192.168.4.0 0.0.1.255

地址前缀列表
R4无法学习到R1的业务网段路由，使用地址前缀列表完成：

[R2]ip ip-prefix q index 2 permit 0.0.0.0 0 less-equal 32

静默接口
因为RIP协议按主类宣告的特点，area 0区域也被宣告进了RIP的管辖区域，故要实现要求5,可以采用静默接口的方法：
[R2]rip 1
[R2-rip-1]silent-interface g0/0/1至此配置完成。
