Configuring and Verifying Standard Access List

Description : This lab exercise demonstrates the concept of Standard Access List by configuring and verifying the same.

Instructions:

1. Connect to R1 and set the IP Address on Ethernet 0 interface to 192.168.1.1/24 and the Serial 0 interface to 192.168.2.1/24 and enable the interfaces. Enable Routing Protocol RIP on R1 and add the network to Ethernet 0 and Serial 0 interfaces

2. Connect to R2 and set the IP Address on Ethernet 0 interface to 192.168.1.2/24, enable the interface and enable RIP on R2, add the network to Ethernet 0 interface

3. Connect to R3 and set the IP Address on Serial 0 interface to 192.168.2.2/24 and Serial 1 interface to 192.168.3.1/24 and enable the interfaces. Enable RIP protocol on R3 and add the network to Serial 0 and Serial 1 interfaces

4. Connect to R4 and set the IP Address on Serial 0 interface to 192.168.3.2/24, enable the interface and enable RIP on R3, add the network to Serial 0 interface

5. Ping R2 from both R3 and R4 and see that it is successful

6. Configure a Standard Access-List on R1 that permits traffic from subnet 192.168.2.0 but blocks traffic from all other devices.

7. Next, apply this access-list to R1ís Serial 0 interface for inbound traffic

8. Verify the access list that is applied on R1 by issuing ping statements i.e, ping R2 from R3 and R4 and check that ping from R3 in subnet 192.168.2.0 is successful whereas ping from R4 in subnet 192.168.3.0 is not successful

9. Now connect to R1 and issue show access-list command which displays the access-lists that are applied on R1

10. Now , try out different cases of applying standard access list and test the same as given below. But before that remove the previously configured Access Lists on R1 by issuing "no ip access group 1 in" command on R1 serial 0 interface and "no access-list 1" command on R1 in global configuration mode
