单臂路由实现vlan 间通信！

UID: 219338

1. 作业要求：

根据拓扑图，实现各个部门都能访问服务器，而他们之间却无法通信！

即 vlan1 vlan10 vlan20 都能顺利访问vlan30 ，而vlan1 vlan10 vlan20之间不能够通信！

2. 拓扑图

3. 设备描述：

路由器：H3C Quidway R2621

交换机：H3C Quidway S3526E

4. 设备配置：

路由器：

[Router]sysname R1

[R1]int e1 // 由于vlan1默认不打标签，如果不设置ip，vlan1 的信息无法通过

[R1- Ethernet 1]ip address 192.168.1.254 24 //配ip

[R1-Ethernet1]int e1.10 //进入子接口

[R1-Ethernet1.10]vlan-type dot1q vid 10 //打标签

[R1-Ethernet1.10]ip add 192.168.10.254 255.255.255.0 //配ip

[R1-Ethernet1.10]int e1.20

[R1-Ethernet1.20]vlan-type dot1q vid 20

[R1-Ethernet1.20]ip add 192.168.20.254 255.255.255.0

[R1-Ethernet1.20]int e1.30

[R1-Ethernet1.30]vlan-type dot1q vid 30

[R1-Ethernet1.30]ip add 192.168.30.254 255.255.255.0

[R1]acl 3000 //访问控制列表

[R1-acl-3000]rule deny ip source 192.168.1.0 0.0.0.255 dest 192.168.10.0 0.0.0.255

Rule has been added to normal pac

[R1-acl-3000]rule deny ip source 192.168.1.0 0.0.0.255 dest 192.168.20.0 0.0.0.255

Rule has been added to normal pac

[R1]acl 3001

[R1-acl-3001]rule deny ip source 192.168.10.0 0.0.0.255 dest 192.168.20.0 0.0.0.255

Rule has been added to normal packet-filtering rules

[R1]int e1.1

[R1-Ethernet1.1]firewall packet-filter ?

<2000-2999> Basic access-list

<3000-3999> Advanced access-list

[R1-Ethernet1.1]firewall packet-filter 3000 //应用访问控制列表

[R1-Ethernet1.1]int e1.10

[R1-Ethernet1.10]firewall packet-filter 3001

交换机：

[s38]vlan 10 //新建vlan

[s38-vlan10]port eth0/10 to eth0/11 //划分端口

[s38-vlan10]vlan 20

[s38-vlan20]port eth0/20 to eth0/21

[s38-Vlan-interface20]vlan 30

[s38-vlan30]port eth0/22 to e0/23

[s38-Vlan-interface30]int eth0/24

[s38-Ethernet0/24]port link-type trunk //trunk链路

[s38-Ethernet0/24]port trunk permit vlan all //允许所有vlan通过,也可以写vlan号

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

5. 测试：

5.1服务器端与客户端之间的配置

服务器端（vlan30）本地连接配置：

[url=http://img1.51cto.com/attachment/201208/16/5635432_1345088639O6Mt.png]

顺序：

先ping本机网关

再ping vlan1网关

再ping vlan10网关 ping vlan10 中的pc

再ping vlan20网关 ping vlan20 中的pc

5.2 客户端之间的测试

客户端设置在vlan20中的pc

上述证明：客户端之间不能通信，即部门之间不能通信
