Setting pada PC dan Server :

PC dan Server	IP Address	Subnet Mask	Default Gateway
PC0	172.16.10.5	255.255.255.0	172.16.10.1
PC1	172.16.40.89	255.255.255.0	172.16.40.1
PC2	172.16.70.5	255.255.255.0	172.16.70.1
PC3	172.16.20.163	255.255.255.0	172.16.20.1
PC4	172.16.50.75	255.255.255.0	172.16.50.1
PC5	172.16.50.7	255.255.255.0	172.16.50.1
PC6	172.16.80.16	255.255.255.0	172.16.80.1
Server	172.16.70.2	255.255.255.0	172.16.70.1

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

Sehingga host 172.16.10.5 tidak akan dapat mengakses host  172.16.40.89 dan 172.16.50.7

Perintah telnet pada router RedDeer :

RedDeer(config)#access-list 20 permit host 172.16.10.5

RedDeer(config)#line vty 0 4

RedDeer(config-line)#access-class 20 in

Hanya host 172.16.10.5 yang dapat melakukan telnet ke router RedDeer.

Sedangkan hasil telnet host lain:
