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

network 192.168.1.0 mask 255.255.255.0
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
AR2
dhcp en
interface GigabitEthernet0/0/0
ip address 192.168.2.254 255.255.255.0
dhcp select global

ip address 10.1.12.2 255.255.255.0
dhcp select global
ospf 1 router-id 2.2.2.2
area 0.0.0.1
network 10.1.12.2 0.0.0.0
network 192.168.2.254 0.0.0.0

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
