Routing between VLANs

Description : This exercise demonstrates the concept of Router on a stick.

Instructions:

1. Configure R1 with sub-interface fastethernet 0/0.10 with IP Address 192.168.100.2 255.255.255.0 and set the encapsulation to dot1q 2 and sub-interface fastethernet 0/0.20 with IP Address 192.168.200.2 255.255.255.0 and set its encapsulation to dot1q 3

2. Check the routing table on R1 by issuing show ip route command

3. Connect to switch SW1 and create VLANs 2 and 3

4. Add the SW1 port fa 0/1 to VLAN 2 using “switchport access vlan <num>” command

5. Add the SW1 port fa 0/2 to VLAN 3 using “switchport access vlan <num>” command

6. Configure the workstation WS1 with IP Address 192.168.100.1 255.255.255.0 and a default-gateway of 192.168.100.2

7. Configure the workstation WS2 with IP Address 192.168.200.1 255.255.255.0 and a default-gateway of 192.168.200.2

8. Ping R1 from WS1 and WS2 and Ping WS2 from WS1 and see that it fails

9. Configure the trunk link between R1 and SW1 by issuing switchport mode trunk command on SW1. Also specify “switchport trunk encapsulation dot1q” on SW1 in interface configuration mode

10. Check the trunk information using show interfaces trunk command

11. Ping R1 from WS1 and WS2 and Ping WS2 from WS1 and see that it is successful as there is a trunk line now created on SW1
