【RIP实验-熟悉基础配置】

实验拓扑

实验要求

根据实验拓扑的IP地址分配，为所有设备配置对应的IP地址和环回地址。
全网运行RIPv2，将R1、R2、R3和R4的物理端口、Loopback地址和10.1.00网段进行宣告。并在rip协议下配置路由自动汇总，观察R1/R2是否能够收到10.0.0.0的详细路由，为什么？
所有路由器关闭自动汇总功能，观察R1/R2是否能够收到10.0.0.0的明细路由，在R2的接口上将该路由进行手动汇总，使R1只能收到10.1.0.0/22的汇总路由。
去R1上观察关于10.1.0.0/22的路由metric值是多少，配置将该路由的metric修改为6。
在R4上观察去23.1.1.0.网段有几个下一跳，配置R4与R2之间网段不发送RIP更新，使R4去23.1.1.0网段只有一个下一跳。
在R1上将1.0.0.0的network去掉，R2、R3和R4这个时候没有路由到达1.0.0.0。配置R1通告一条默认路由给R2、R3和R4。
恢复R2与R4之间发送RIP更新，在R2上观察去34.1.1.0网段有几个下一跳，改变RIP的默认最大可用路径，使之只有一个下一跳。

实验分析

略。
R1和R2上没有到10.0.0.0的详细路由，因为自动汇总，匹配的是自然掩码，10.0.0.0匹配的掩码是8.
关闭自动汇总后，R1和R2上有10.0.0.0的明细路由，因为开启的是RIPv2，支持VLMS。接口上手动汇总的命令是rip summary-address 10.1.0.0 255.255.252.0
由于RIP是根据跳数计算度量值，所以metric的值为2，修改metric的命令为rip metricin 2000 5
ACL策略为：
rule permit source 10.1.0.0 0.0.255.255
rule deny
（答案不唯一）
由于R4既与R3相连又与R2相连，且没有修改cost值，因此有个下一跳。配置不发送RIP更新的命令为：silent-interface GigabitEthernet 0/0/2（配置完，需要等待180秒左右，路由才会老化，才会有效果）
在R1上引入直连路由，命令为：import-route direct
有2条到达34.1.1.0的下一条，改变RIP默认的最大可用路径的命令为：maximum load-balancing 1
