一、网络环境

1.网络拓扑

2.网络互通链接

中小型局域网规划实战案例

二、ACL要求

1.要求部门A不能访问部门B
2.要求所有部门不可以ping通服务器区域，但能访问web服务器
3.部门D不能访问部门C

三、ACL实施

1.部门A禁止访问部门B

[SW2]acl 3001
[SW2-acl-adv-3001]rule deny ip source 192.168.10.0 0.0.0.255 destination 192.168
.20.0 0.0.0.255
[SW2-acl-adv-3001]quit    
[SW2-GigabitEthernet0/0/3]traffic-filter inbound acl

PC>ping 192.168.20.222

2.服务器区域ACL配置

[SW2]acl 3002    
[SW2-acl-adv-3002]rule deny ip source any destination 172.16.10.0 0.0.0.255

[SW2-acl-adv-3002]rule permit ip source 192.168.10.222 0 destination 172.16.10.2

[SW2-acl-adv-3002]rule permit tcp destination 172.16.10.250 0 destination-port e
q 80
[SW2-acl-adv-3002]quit
[SW2]interface GigabitEthernet 0/0/6
[SW2-GigabitEthernet0/0/6]traffic-filter inbound acl 3002
[SW2-GigabitEthernet0/0/6]

3.部门D不能访问部门C

[SW2]acl 3003    
[SW2-acl-adv-3003]rule deny ip source 192.168.40.0 0.0.0.255 des    
[SW2-acl-adv-3003]rule deny ip source 192.168.40.0 0.0.0.255 destination 192.168
