实验目的：
RIPV2是RIP的第二代协议，它与RIP的主要区别在于一个是RIP发包走的是广播，RIPv2发包走的是组播，另外一个就是RIPv2支持变长VLSM可扩展的子网掩码，支持手动汇总，通过实验观察RIPv2如何支持VLSM以及自动汇总与手动汇总的区别。
实验拓扑：
实验内容：
1.路由器的基本配置
R1上的基本配置
interface Loopback1
ip address 1.1.1.1 255.255.255.0
!
（为了测试RIPV2的汇总我们在这里起用了5个环回接口）
interface Loopback2
ip address 10.1.1.1 255.255.255.0
!
interface Loopback3
ip address 10.1.2.1 255.255.255.0
!
interface Loopback4
ip address 10.1.3.1 255.255.255.0
!
interface Loopback5
ip address 10.1.4.1 255.255.255.0
!
interface Loopback6
ip address 10.1.5.1 255.255.255.0
!
interface Ethernet0
ip address 192.168.10.1 255.255.255.0
interface Serial0
ip address 192.168.2.1 255.255.255.0
clockrate 64000
R2上的基本配置
interface Serial0
ip address 192.168.3.1 255.255.255.0
clockrate 64000
!
interface Serial1
ip address 192.168.2.2 255.255.255.0
R3上的基本配置
interface Loopback0
ip address 3.3.3.3 255.255.255.0
!
interface Ethernet0
ip address 192.168.10.2 255.255.255.0
!
interface Serial0
no ip address
shutdown
!
interface Serial1
ip address 192.168.3.2 255.255.255.0
2．配置RIP,并提升为v2版本,为各个路由器起RIP
将RIP提升为V2版本的命令如下：
router(config )#router rip
router(config-route)#version 2
R1上的RIP配置
router rip
version 2（注：比较与RIPV1的不同，此处多了一个version 2）network 1.0.0.0
network 10.0.0.0
network 192.168.2.0
network 192.168.10.0
R2上的RIP配置
router rip
version 2
network 192.168.2.0
network 192.168.3.0
R3上的RIP配置
router rip
version 2
network 3.0.0.0
network 192.168.3.0
network 192.168.10.0
3．查看此时的路由表
R1上的路由表
R1#show ip route
