Configuring and Verifying Extended Access List

Description : This lab exercise demonstrates the concept of Extended 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 Extended Access-List 101 on R1 that allows telnet traffic from R3 (192.168.2.2) and allow icmp traffic from R4 (192.168.3.2) and block all other traffic

7. Apply this access-list to R1ís Serial 0 interface on inbound traffic and check the same using show ip interface command

8. Verify the Extended Access List applied on R1 by pinging and telneting R2 from R3 and R4

(R3 (192.168.2.2)) should not be able to ping R2 but should be able to telnet to R2 and R4 (192.168.3.2) should be able to ping R2 but not telnet to it))
