Lab 21: Configuring Static Routing via IP addresses

Lab Objective:

The objective of this lab exercise is to configure static routes via next hop IP addresses on 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 sever and configure VLAN10 named STATIC. Assign ports FastEthernet0/1 and FastEthernet0/2 to this VLAN.

Task 3:

Configure IP addresses 172.27.32.1/30 and 172.27.32.2/30 on R1 and R2 Fa0/0 interfaces, respectively. In addition, configure the Loopback interfaces on R1 with the IP addresses in the topology.

Task 4:

Configure static routes via the next hop IP address of 172.27.32.2 on R2 to all the subnets configured on the Loopback addresses previously configured on R1. Verify your static route configuration. 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: Notice the difference in this ping versus the one where you used an interface as the next hop for static routing. Because an IP address has been specified, there is no ARP timeout for the first packet since the next hop Layer 3 address has been specified.
