Lab 15:
Configuring and allowing inter-VLAN routing
Lab Objective:
The objective of this lab exercise is to configure a router to provide inter-VLAN communication. By default, hosts in one VLAN cannot communicate with hosts in another VLAN without a router routing between the two VLANs.
Lab Purpose:
Inter-VLAN routing configuration is a fundamental skill. Most networks typically have more than one VLAN and it is a requirement that hosts in these VLANs communicate with each other if the need arises. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure inter-VLAN routing.
Certification Level:
This lab is suitable for CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 9/10
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 20 minutes
Lab Topology:
Please use the following topology to complete this lab exercise:
Task 1:
Configure a hostname on switches 1 and 2 and routers 1 through 4 as illustrated in the topology above.
Task 2:
Configure and verify Sw1 and Sw2 as VTP Transparent switches. Both switches should be in the VTP domain named CISCO. Secure VTP messages with the password CISCO.
Task 3:
Configure and verify FastEthernet0/1 between Sw1 and Sw2 as an 802.1q trunk and configure VLANs as depicted in the topology above. Assign ports to depicted VLANs and configure Sw1 FastEthernet0/2 as a trunk. VLAN 20 should have untagged Ethernet Frames. Remember that on 802.1q trunks, only the native VLAN is untagged.
Task 4:
Configure IP addresses on routers R2, R3, and R4 as illustrated in the diagram.
Task 5:
Configure subinterfaces off FastEthernet0/0 in the corresponding VLANs on the diagram. Also configure interface VLAN 10 on switch Sw2 with the IP address 10.0.10.2/28.
Task 6:
Test network connectivity by pinging from R1 to routers R2, R3, and R4.
