Perintah ACL pada RedDeer:

RedDeer(config)#access-list 10 deny 172.16.10.0 0.0.0.255

RedDeer(config)#access-list 10 permit any

RedDeer(config)#int fa0/0

RedDeer(config-if)#ip access-group 10 out

Perintah ACL pada Edmonton:

Edmonton(config)#access-list 115 deny ip host 172.16.10.5 host 172.16.50.7

Edmonton(config)#access-list 115 permit ip any any

Edmonton(config)#int fa0/0

Edmonton(config-if)#ip access-group 115 in
