Rip实验
实验拓扑图
1 r1为isp 其上只能配置ip地址，不得进行其他配置
2 r7环回地址172.16.1.0/24
R8环回地址172.16.2.0/24
R7-r8之间地址为78.1.1.0/24
3. r2到r5环回通过r3访问
4 加快协议收敛速度，保证更新安全 尽量减少路由条目
5 r2-r8设备均可访问r1环回
6 r1telnet r2实际登陆到r8
一、地址规化
路径 Ip网段 路径 ip网段
R2-r3 192.168.1.0/30 R7-r8 78.1.1.0/24
R3-r4 192.168.1.4/30 R7环回 172.16.1.0/24
R4-r5 192.168.1.8/30 R8环回 172.16.2.0/24
R5-r6 192.168.1.12/30
R6-r2 192.168.1.16/30
R6-r7 192.168.1.20/30
R1-r2 192.168.1.24/30
R2环回 192.168.1.32/28 192.168.1.48/28
R3环回 192.168.1.64/28 192.168.1.80/28
R4环回 192.168.1.96/28 192.168.1.112/28
R5环回 192.168.1.128/28 192.168.1.144/28
R6环回 192.168.1.160/28 192.168.1.176/28
R1环回 192.168.1.192/27
二、r2到r5环回通过r3访问
1）在r6中使用acl抓取r5环回地址，在r6与r2接口使用偏移列表增大metric值
2）在r6中使用acl抓取r5环回地址，在r6与r5接口使用偏移列表增大metric值
3）在r2中使用acl抓取r5环回地址，在r2到r6的接口使用偏移列表增大metric值
三、ripv2与ripv1之间互通，
修改r7上接收版本让ripv1与ripv2之间吸纳和学习，r7与r8之间使用第二地址组成rip连续子网让r7-r8相互学习对方环回
四、加快协议收敛速度，保证更新安全，尽量减少路由条目数量
通过修改计时器时间加快协议收敛速度
使用认证保证更新安全（只能使用在ripv2中）
汇总减少路由条目
对各个路由环回路由汇总

五、r2-r8设备均可以访问r1环回
在r2上写静态路由指向r1，并作缺省路由，划分nat。
六、r1 telnet r2实际登陆到r8上
