基于DHCP,ACL的通信

该问题为华为的学习资料

1.首先把所有的PC机全部设置为DHCP

2.配置地址

3.ospf

4.dhcp

5.acl

AR1
dhcp en
interface GigabitEthernet0/0/0
 ip address 192.168.1.254 255.255.255.0 
 dhcp select global
interface GigabitEthernet0/0/1
 ip address 10.1.12.1 255.255.255.0 
 dhcp select global
ospf 1 router-id 1.1.1.1

 excluded-ip-address 192.168.1.3 192.168.1.253         /设置不在DHCP分配范围之类的地址

tsunpm
int g 0/0/2
 traffic-filter outbound acl 3001                /注意outbound是针对出,inbound是针对入

结果:

 

PC1无法ping通PC3,其他PC之间均是可以通信的

因个人能力有限,笔者发现,在使用acl时,不知在permit时间范围以外,pc1给pc3的报文是否是默认拒绝通过,还有待验证,

如有问题,可以使用更好的时间范围,或者多个时间范围的联合, 注意192.168.2.252是DHCP自动获取的地址

如有错误,还请指正
