s5 s6 配置与s4类似此处省略
R1 R2 只需配置好每个端口ip然后配置ospf协议，端口ip和路由协议配置与核心交换机类似此处省略。

 总结

1.题目要求可扩展的局域网组建

实验过程用了vtp

vtp是思科私有协议，若扩展使用别的厂商设备如华为就达不到可扩展性的要求

其实完全可以自己手工划分下vlan，使用vtp只是为了方便

2.使用三层交换的时候记得两条条命令

ip routing

和

no shut

我在配置了ospf协议后彼此之间学习不到路由信息

郁闷了半天才发现忘了ip routing 来启用三层交换的路由功能

 

补充：

毕业设计的实验目的达到了，

但是实际应用过程中还需要添加不少东西

比如说远程telnet管理

现添加如下

 

配置交换路由的密码（每个交换机都做此配置，密码为net）

en
config

enable pass net
line vty 0 4
pass net
login

 配置汇聚和接入层交换机的管理地址（根据上表，不同交换机配置不同ip，配置类似只写一条代替）

config

int vlan 1

ip add 192.168.254.2 255.255.255.0
no shut

ip default-gateway 192.168.254.1

 

在教学楼和办公楼交换机上做一条ospf路由

使在两边的任意电脑都可以ping通任意交换机的管理地址

router ospf 1
jiaoxue(config-router)#network 192.168.254.0 0.0.0.255 area 0

 

教学楼汇聚交换机的管理地址254.1作为教学楼接入交换机的default-gateway

办公楼汇聚交换机的管理地址254.9作为办公楼接入交换机的default-gateway
s3未配置default-gateway，用来与s1，s2做对比。
在s1下的pc机上ping s3的管理地址不通，ping s2通。
给交换机配置管理接口地址（一般是vlan1的地址）和default gateway后
才可以在不同的vlan下的pc机上telnet管理交换机。
之所以配置交换机的default-gateway，是把交换机当做一台pc机，它也需要有自己的网关地址。
