大家好,这里是G-LAB IT实验室。今天我们带大家学习如何搭建企业网络

实验拓扑

拓扑需求
交换部分:
1.将SW1-SW2间的e0/0/5、e0/0/6配置为手工方式的eth-trunk,链路编号为eth-trunk 12
2.将SW1、SW2、SW3、SW4间的所有链路配置为trunk
3.在SW1、SW2、SW3、SW4上创建vlan10、vlan20、vlan11、vlan12
4.在SW1、SW2、SW3、SW4上开启STP协议
5.将SW1设置为所有VLAN的根交换机,将SW2设置为所有VLAN的备份根交换机
6.将PC3、PC4划入vlan10、将PC7、PC8划入vlan20
路由部分:
1.IP地址规划如下:
vlan10 ----------- 10.1.10.0/24
vlan20 ----------- 10.1.20.0/24
vlan11 ----------- 10.1.11.0/24
vlan12 ----------- 10.1.12.0/24
R1-R2 ------------ 12.1.1.0/24
R2-Client2 ------------ 20.1.1.0/24
2.将SW1设置为vlan10、vlan20的网关,IP地址为vlan对应网段的最后一个可用IP
3.将SW2设置为vlan10、vlan20的备份网关,IP地址为vlan对应网段的倒数第二个可用IP
4.将SW1的e0/0/1接口划入vlan11,并为vlan11配置对应网段的第一个可用IP
5.将SW2的e0/0/1接口划入vlan12,并为vlan12配置对应网段的第一个可用IP
6.将R1的g0/0/0接口IP配置为10.1.11.0/24网段的最后一个可用IP
7.将R1的g0/0/1接口IP配置为10.1.12.0/24网段的最后一个可用IP
8.配置R1-R2相连接口的IP地址,R1配置网段第一个可用IP,R2配置网段第二个可用IP
9.配置R2-Client2相连接口的IP地址,Client2配置网段第一个可用IP,R2配置网段最后一个可用IP
10.在SW1、SW2、R1间运行OSPF 100,将vlan10、vlan20、vlan11、vlan12对应网段宣告进area0
11.在R1上添加缺省静态路由,将下一跳指向R2
12.在R1上将缺省静态路由发布进OSPF 100
13.在R1-R2间运行OSPF 200,将R1-R2间网段以及R2-Client2间网段宣告进area0
访问控制部分:
1.在R1上配置PAT,让vlan10、vlan20内的所有主机共用12.1.1.10/24这个IP访问Client2
2.要求vlan10内的主机可以访问Client2的web服务,但不能访问Client2的ftp服务;vlan20内的主机可以访问Client2的ftp服务,但不能访问Client2的web服务;其余流量不做限制
