交换机路由器简单搭建（华为）

 

 

局域网内不同vlan间通过dhcp实现通信

             

 

 

 

姓名：刘凡

 

运用技术:

路由器中继 ip relay-address …….

路由器snat dnat 转换

控制列表建立

路由器子接口vlan划分

交换机vlan划分

交换机端口设置trunk

Dhcp服务器配置

www服务器配置

路由器

 

E1端口 192.168.101.23

路由器划分vlan和实现中继

Int e0.1

Vlan-type dot1q vid10

Int e0.2

Vlan-type dot1q vid20

Ip relay-address192.168.30.3

Int e0.1

Ip relay-address192.168.30.3

 

路由器实现snat和dnat转换：

acl 2000(建访问控制列表)

rule permit source 192.168.30.0 0.0.0.255

rule deny source any

quit

nat bound 2000 interface   #(SNAT)

inter e1

nat server global 192.168.101.23 80 inside 192.168.30.3 80 tcp    #(DNAT)

 

 

 

Linux作为dhcp服务器

subnet 192.168.10.0 netmask 255.255.255.0 {

        # we want the nameserver to appear at a fixed address

}

www服务器配置

linux上安装www服务器

[root@localhost ~]# mount /dev/cdrom /mnt/cdrom

mount: block device /dev/cdrom is write-protected, mounting read-only

[root@localhost ~]# cd /mnt/cdrom/Server

[root@localhost Server]# ll httpd*

交换机1

14和18口设置为trunk

14路由器18交换机

E0/10为10网段

E0/20为20网段

E0/15为30网段

[sw1]vlan 10

[sw1-vlan10]port e0/10

[sw1-vlan10]vlan 20

[sw1-vlan20]port e0/20

[sw1-vlan20]vlan 30

[sw1-vlan30]port e0/15

[sw1-Ethernet0/20]inter e0/14

[sw1-Ethernet0/14]port link-type trunk

[sw1-Ethernet0/20]inter e0/18

[sw1-Ethernet0/18]port link-type trunk

交换机2

22端口trunk

E1/0/10为10网段

E1/0/20为20网段

E1/0/15为30网段

 

[sw2-Ethernet1/0/22]quit

[sw2]vlan 10

[sw2-vlan10]port e1/0/10

[sw2-vlan10]vlan 20

[sw2-vlan20]port e1/0/20

[sw2-vlan20]vlan 30

[sw2-vlan30]e1/0/15

            ^

 % Unrecognized command found at '^' position.

[sw2-vlan30]port e1/0/15

[sw2-vlan30]

[sw2]inter e1/0/22

[sw2-Ethernet1/0/22]port link-type trunk

[sw2-Ethernet1/0/22]port trunk permit vlan all

 Please wait........................................... Done.

 

然后找一台pc机接sw1 10端口测试是否能获得10.0地址

再试20端口，交换机2也是如此

 

测试www服务器

用此主机访问192.168.30.3
