Lab – Troubleshooting Basic Frame Relay

Background / Scenario
Frame Relay is a WAN protocol that operates at the physical and data link layers of the OSI reference model.
Unlike leased lines, Frame Relay requires only a single-access circuit to the Frame Relay provider to
communicate with multiple sites that are connected to the same provider. Configuring Frame Relay at the
customer site is generally simple; however, configuration problems can occur.
In this lab, R1 and R3 are experiencing problems communicating with each other. EIGRP is not working and
there may also be problems with the Frame Relay configuration. You have been assigned the job of finding
and correcting all problems on R1 and R3.
Note: The routers used with CCNA hands-on labs are Cisco 1941 Integrated Services Routers (ISRs) with
Cisco IOS Release 15.2(4)M3 (universalk9 image). Other routers and Cisco IOS versions can be used.
Depending on the model and Cisco IOS version, the commands available and output produced might vary
from what is shown in the labs. Refer to the Router Interface Summary Table at the end of this lab for the
correct interface identifiers.
Note: Make sure that the routers have been erased and have no startup configurations. If you are unsure,
contact your instructor.
Note: The FR router is acting as the Frame Relay switch, It does NOT have any configuration issues for you
to troubleshoot.
Instructor Note: Refer to the Instructor Lab Manual for the procedures to initialize and reload devices.
Required Resources
3 Routers (Cisco 1941 with Cisco IOS Release 15.2(4)M3 universal image or comparable)
2 PCs (Windows 7, Vista, or XP with terminal emulation program, such as Tera Term)
Console cables to configure the Cisco IOS devices via the console ports
Ethernet and serial cables as shown in the topology
Part 1: Build the Network and Load Device Configurations
Step 1: Cable the network as shown in the topology.
Step 2: Configure addressing on the PCs.
Step 3: Load router configuration files.
Load the following configurations into the appropriate router. R1 and R3 have the same passwords. The
encrypted privileged EXEC mode password is class, and the password for console and vty access is cisco.
Router R1 Configuration:
hostname R1
enable secret class
no ip domain lookup
interface GigabitEthernet0/0
ip address 192.168.1.1 255.255.255.0
