Part 3: IP Addressing, Routing, and WANs
Lab 5: Connected Routes
Overview
In this lab, you’ll learn how to use and interpret the show ip route connected command. You’ll begin with R1’s interfaces fully configured. R2’s interfaces are partially configured and both are shut down. You’ll bring them up and see the effects.

Detailed Lab Steps
Step 1. Step 2.

Connect to R1 from the simulator user interface; use password ciscopress. Enter privileged exec mode by issuing the enable command; use password ciscopress.

Step 3.

Issue the show ip route connected command and view the output. How many connected routes do you see? Which ones are they? 0

Step 4.

Connect to R2 from the simulator user interface and enter privileged exec mode using the enable command. All passwords are ciscopress. Repeat Step 3 on R2. How many connected routes do you see? Which ones are they? 0

Step 5.

Step 6.

Use the show ip interface brief command. Is there an IP address listed for interface S0/0/1? Interface Fa0/0? yes

no Routers cannot add a connected route to the routing table unless the interface is in an “up and up” state. The following steps enable R2’s two interfaces:
Step 7.

Move into interface configuration mode for interface S0/0/1 by using the configure terminal command followed by the interface s0/0/1 command. Enable the interface using the no shutdown command. Repeat Steps 7 and 8 for interface FastEthernet 0/0. Record the configuration commands you use. interfaceFA0/0 NoShutdown

Step 8. Step 9.

Step 10. Step 11.

Exit configuration mode either by entering end or by
