Lab Objective:
The objective of this lab exercise is to configure static routes via Ethernet interfaces connected to a switch on two routers. This lab also goes through the validation of the configured static routes.
Lab Purpose:
Static route configuration is a fundamental skill. There are several methods to configure static routes on a Cisco router, and each way has its pros and cons. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure static routes via any of the methods available in Cisco IOS.
Certification Level:
This lab is suitable for both CCENT and CCNA certification exam preparation.
Lab Difficulty:
This lab has a difficulty rating of 5/10.
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 hostnames on R1, R2, and Sw1 as illustrated in the topology.
Task 2:
Configure Sw1 as a VTP server and configure VLAN10 named STATIC. Assign ports FastEthernet0/1 and FastEthernet0/2 to this VLAN.
Task 3:
Configure IP addresses 172.27.32.1/19 and 172.27.32.2/19 on R1 and R2 Fa0/0 interfaces, respectively. In addition, configure the Loopback interfaces on R1 with the IP addresses listed in the topology.
Task 4:
Configure static routes via the FastEthernet0/0 interface on R2 to all the subnets configured on the Loopback addresses configured on R1. Verify your static route configuration with appropriate commands. Ping each Loopback interface configured on R1 from R2 to validate your static route configuration.
Configuration and Verification
Task 1:
For reference information on configuring hostnames, please refer to earlier labs.
Task 2:
For reference information on configuring standard VLANs, please refer to earlier labs.

NOTE: By default, Loopback interfaces will be enabled once you configure them. Therefore, there is no need to issue the no shutdown command when creating them.
