简单acl实验

设置acl，就远原则，AR1的g0/0/0端口配置，对应PC1目标端口AR1需要icmp拒绝pc1，目标端口AR2需要tcp拒绝pc1，PC2与PC1配置原理相同

[AR1]int g0/0/1
[AR1-GigabitEthernet0/0/1]ip add 192.168.2.1 24
[AR1-GigabitEthernet0/0/1]int g0/0/0
[AR1-GigabitEthernet0/0/0]ip add 192.168.1.1 24

[AR2]int g0/0/0
[AR2-GigabitEthernet0/0/0]ip add 192.168.2.2 24
[AR2]ip route-static 192.168.1.0 24 192.168.2.1

[PC1]int g0/0/0
[PC1-GigabitEthernet0/0/0]ip add 192.168.1.10 24
[PC1]ip route-static 0.0.0.0 0 192.168.1.1

[PC2]int g0/0/0
[PC2-GigabitEthernet0/0/0]ip add 192.168.1.11 24
[PC2]ip route-static 0.0.0.0 0 192.168.1.1

开启telnet功能
[AR1]aaa
[AR1-aaa]local-user zzq privilege level 15 password cipher 123456
[AR1-aaa]local-user zzq service-type telnet 
[AR1]user-interface vty 0
[AR1-ui-vty0]authentication-mode aaa

[AR2]aaa
[AR2-aaa]local-user zzq privilege level 15 password cipher 123456
[AR2-aaa]local-user zzq service-type telnet 
[AR2]user-interface vty 0 4
[AR2-ui-vty0-4]authentication-mode aaa

创建ACL
[AR1]acl 3000
[AR1-acl-adv-3000]rule deny icmp source 192.168.1.10 0.0.0.0 destination 192.168.1.1 0.0.0.0 
[AR1-acl-adv-3000]rule deny icmp source 192.168.1.10 0.0.0.0 destination 192.168.2.1 0.0.0.0
