Lab Objective:
The objective of this lab exercise is for you to learn and understand how to configure inter-VLAN routing using switched virtual interfaces (SVIs). This is technically in the ICND2 syllabus but inter-VLAN routing is also in the CCENT syllabus, so we’ll cover it now.

Lab Purpose:
Understanding inter-VLAN routing and your configuration options is a vital skill for the exam and for administering live networks. You will need access to a Layer 3 switch for this lab, such as a 3560 (or use Packet Tracer).

Certification Level:
This lab is suitable for CCENT and ICND2 certification exam preparation.

Lab Difficulty:
This lab has a difficulty rating of 7/10.

Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 15 minutes.

Lab Topology:
Please use the following topology to complete this lab exercise:


Task 1:
Configure the host IP addresses as well as VLANs 10 and 20 on the switch. Put the correct interfaces into the correct VLANs.

Task 2:
Configure SVIs on the switch for VLANs 10 and 20 of and

Task 3:
Verify your configuration with the correct show commands.

Task 4:
Enable IP routing on the switch. Then, test your configurations by pinging from a host in VLAN10 to a host in VLAN20.

Configuration and Verification
Task 1:
For the hosts, you will need to manually add the IP addresses. Choose any addresses from the subnet but do not use the IPs required for the SVIs. Add the SVI IP address to the hosts as the default gateway. If your switch doesn’t support the interface range facility, then configure each interface individually.

You may not be familiar with the switchport command because Layer 3 switches aren’t covered in the theory part of the CCNA exam. This command specifies the interface to work as Layer 2 as opposed to an IP interface (as you would see on a router Ethernet port).

Switch(config-vlan)#name VLAN-10
Switch(config-vlan)#name VLAN-20
Switch(config)#interface range FastEthernet0/1 – 2
Switch(config-if-range)#switchport mode access
Switch(config-if-range)#switchport access vlan10
Switch(config)#interface range FastEthernet0/3 – 4
Switch(config-if-range)#switchport mode access
Switch(config-if-range)#switchport access vlan20
Task 2:
Switch(config)#interface vlan10
Switch(config-if)#description “SVI for VLAN 10”
Switch(config-if)#ip address
Switch(config-if)#no shutdown
Switch(config)#interface vlan20
Switch(config-if)#description “SVI for VLAN 10”
Switch(config-if)#ip address
Switch(config-if)#no shutdown
Task 3:
Switch#show vlan brief
