1.Connect to R1 and configure the IP address of on the fastethernet interface and set the interface up by issuing no shutdown command

2.Connect to workstation WS1 and set its IP address to and default-gateway to, and then connect to WS2 and set its IP address to and default-gateway to

3. Ping R1 and WS1 from WS2 and see that the ping is successful

4. Connect to Switch SW1 and set up the VLANs. Start by creating VLAN 20 to set up a separate VLAN for the WRS (workstations)

5. Now assign ports to the new VLAN , assign port 1 for WS1 to VLAN 20

6. Connect to WS2 again and try to ping R1 and WS1
Ping is success from WS2 to R1 but not from WS2 to WS1, this is because on the switch, VLAN 20 is set to cover only port 1)

7. Connect to SW1 again and now configure port 2 wherein WS2 is connected, to be included in VLAN 20

8. Repeat the pings from WS2 to R1 and WS1.This time ping to WS1 would be successful but not to R1 (This is because when the ping packets came in, they were tagged with VLAN 20. Consequently, the packets could only travel out port 1 to WS1)

9. Connect to SW1 again and issue appropriate show commands to view the VLAN port assignments

10. Now on SW1, assign fastethernet 0/12 to VLAN 20 . This would allow to ping all of the devices

11. Issue pings from R1 to WS1 and WS2 and from WS1 and WS2 to R1 and check the connectivity
