1.技术原理 RIP(Routing Information Protocols,路由信息协议)是应用较早、使用较普遍的 IGP内部网管协议，使用于小型同类网络，是距离矢量协议；

RIP 协议跳数作为衡量路径开销的，RIP 协议里规定最大跳数为 15；跳计数 16 则表示目标不可达。

RIP 协议有两个版本：RIPv1 和 RIPv2，RIPv1 属于有类路由协议，不支持 VLSM，以广播形式进行路由信息的更新，更新周期为 30 秒；RIPv2 属于无类路由协议，支持 VLSM，以组播形式进行路由更细。

RIP 是一个距离矢量的路由协议，它是定期的更新，默认时间30S，也就是说如果刚刚发送过更新，即使网络拓扑发生了变化，路由器也不进行更新，要等待下一个更新周期才发送更新。 2.拓扑图

3.配置PC PC0 IP: 192.168.1.2 Submask: 255.255.255.0 Gateway: 192.168.1.1 PC1 IP: 192.168.2.2 Submask: 255.255.255.0 Gateway: 192.168.2.1 4.配置交换机

Creating vlan 10 Switch(config-if)#int f0/20 Switch(config-if)#switchport access vlan 20 % Access VLAN does not exist.

Switch#show vlan Switch#config t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#int vlan 10 Switch(config-if)# %LINK-5-CHANGED: Interface Vlan10, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan10, changed state to up

Switch(config-if)#ip add 192.168.1.1 255.255.255.0 Switch(config-if)#no shu Switch(config-if)# Switch(config-if)#int vlan 20 Switch(config-if)# %LINK-5-CHANGED: Interface Vlan20, changed state to up

Switch(config-if)#ip add 192.168.3.1 255.255.255.0 Switch(config-if)#no shu Switch(config-if)# Switch(config-if)#exit Switch(config)#ip routing Switch(config)#router rip Switch(config-router)#network 192.168.1.0 Switch(config-router)#network 192.168.3.0 Switch(config-router)#version 2 Switch(config-router)#end Switch#

5.配置router0

Router>en Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#int f0/0 Router(config-if)#no shu

Router(config-if)# %LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

Router(config-if)#ip add 192.168.3.2 255.255.255.0 Router(config-if)#int s2/0 Router(config-if)#ip add 192.168.4.1 255.255.255.0 Router(config-if)#no shu

%LINK-5-CHANGED: Interface Serial2/0, changed state to down Router(config-if)# Router(config-if)#clock rate 64000 Router(config-if)#exit Router(config)#router rip Router(config-router)#network 192.168.3.0 Router(config-router)#network 192.168.4.0 Router(config-router)#version 2 Router(config-router)#

6.配置router1

Router>en Router#config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#int s2/0 Router(config-if)#ip add 192.168.4.2 255.255.255.0 Router(config-if)#no shu

Router(config-if)# %LINK-5-CHANGED: Interface Serial2/0, changed state to up

Router(config-if)#int f0/0 Router(config-if)#ip add 19 %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial2/0, changed state to up 2.168.2.1 255.255.255.0 Router(config-if)#no shu

Router(config-if)# %LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

Router(config-if)#exit Router(config)#router rip Router(config-router)#network 192.168.4.0 Router(config-router)#network 192.168.2.0 Router(config-router)#version 2
