RIP版本之间传递路由信息

2.1．1实验目的：
在路由器R2上配置RIPv1，在R6和R3上配置RIPv2，要求R6、R3能接收到路由器R2的路由信息。

2.1．2实验拓扑：





2.1.3实验配置：
R2的配置：

network 2.0.0.0
network 26.0.0.0
R6的配置：
interface Loopback0
ip address 6.6.6.6 255.255.255.0
interface Serial0/2
ip address 26.26.26.6 255.255.255.0
interface Serial0/3
ip address 36.36.36.6 255.255.255.0
router rip
version 2
network 6.0.0.0
network 26.0.0.0

network 36.0.0.0
2.1.4实验验证：
配置完成后，测试一下 可以看到：
R2可以ping通r6 r3任何一个接口 查看路由表：
R2#show ip route

o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

2.2RIPV2的手工汇总
2.2.1实验目的：
RIPv2是无类协议，支持可变字长掩码（VLSM） ，而 RIPv1是有类协议，只支持固定
长度的子网掩码。因此在 RIPv2中可以执行手工汇总，而 RIPv1不能。此外 RIPv2默认开
启自动汇总。
