Lab 3.5.2 – Challenge Frame Relay Configuration (Answers)

Topology Diagram

Addressing Table

Learning Objectives

Upon completion of this lab, you will be able to:

• Cable a network according to the topology diagram
• Erase the startup configuration and reload a router to the default state
• Perform basic configuration tasks on a router
• Configure and activate interfaces
• Configure EIGRP routing on all routers
• Configure Frame Relay encapsulation on all serial interfaces
• Configure a Frame Relay PVC
• Intentionally break and restore a Frame Relay PVC
• Configure Frame Relay subinterfaces
• Intentionally break and restore the PVC

Scenario

In this lab, you will configure Frame Relay using the network shown in the topology diagram. If you need assistance, refer to the Basic Frame Relay lab. However, try to do as much on your own as possible.

Task 1: Prepare the Network

Step 1: Cable a network that is similar to the one in the topology diagram.

Step 2: Clear any existing configurations on the routers.

Task 2: Perform Basic Router Configuration

Configure the R1, R2, and R3 routers according to the following guidelines:

• Configure the router hostname.
• Disable DNS lookup.
• Configure an EXEC mode password.
• Configure a message-of-the-day banner.
• Configure a password for console connections.
• Configure synchronous logging.
• Configure a password for vty connections.

Task 3: Configure IP Addresses

Step 1: Configure IP addresses on all links according to the addressing table.

R1

R1(config)#int s0/0/0
R1(config-if)#ip address 10.1.2.1 255.255.255.252
R1(config-if)#int fa0/1
R1(config-if)#ip address 172.16.1.254 255.255.255.0

R2:

R2(config)#int s0/0/1
R2(config-if)#ip address 10.1.2.2 255.255.255.252 
R2(config-if)#int fa0/1
R2(config-if)#ip address 172.16.1.254 255.255.255.0

Step 2: Verify IP addressing and interfaces.

Step 3: Activate Ethernet interfaces of R1 and R2. Do not activate the serial interfaces.

R1(config-if)#int fa0/1
R1(config-if)#no shut

R2(config-if)#int fa0/1
R2(config-if)# no shut

Step 3: Configure the Ethernet interfaces of PC1 and PC3.

Step 4: Test connectivity between the PCs and their local routers.

Task 4: Configure EIGRP on Routers R1 and R2

Step 1: Enable EIGRP on R1 and R2 for all subnets.

router eigrp 1
network 10.1.2.0 0.0.0.3
network 172.16.0.0 0.0.15.255.255
no auto-summary

Task 5: Configure Frame Relay PVC Between R1 and R2

Step 1: Configure interfaces on FR-Switch to create the PVC between R1 and R2.

Use the DLCIs in the topology diagram.

FR-Switch:
interface serial0/0/0
encapsulation frame-relay
frame-relay route 102 interface s0/0/1 201
frame-relay intf-type dce
interface serial0/0/1
encapsulation frame-relay
frame-relay route 201 interface s0/0/0 102
frame-relay intf-type dce

Step 2: Configure physical interfaces on R1 and R2 for Frame Relay encapsulation.

Do not automatically discover IP addresses on the far end of links. Activate the link after full configuration.

R1

interface serial0/0/0
encapsulation frame-relay
no frame-relay inverse-arp
no shut

R2

int s0/0/1
encapsulation frame-relay
no frame-relay inverse-arp
no shut

Step 3: Configure Frame Relay maps on R1 and R2 with proper DLCIs. Enable broadcast traffic on the DLCIs.

R1

interface serial0/0/0
frame=relay map ip 10.1.2.2 102 broadcast

R2

interface serial0/0/1
frame-relay map ip 10.1.2.1 201 broadcast

Step 4: Verify end-to-end connectivity using PC1 and PC2.

ping

Task 6: Intentionally Break the PVC and Then Restore It

Step 1: By a means of your choosing, break the PVC between R1 and R2.

Step 2: Restore full connectivity to your network.

Step 3: Verify full connectivity to your network.

Task 7: Configure Frame Relay Subinterfaces

Step 1: Remove the IP address and frame map configuration from the physical interfaces on R1 and R2.

R1

interface serial0/0/0
no frame-relay map ip 10.1.2.2 102 broadcast
no ip address

R2

int s0/0/1
no frame-relay map ip 10.1.2.1 201 broadcast

Step 2: Configure Frame Relay point-to-point subinterfaces on R1 and R2 with the same IP addresses and DLCI used earlier on the physical interfaces.

R1

interface serial0/0/0.102 point-to-point
ip address 10.1.2.1 255.255.255.252
frame-relay interface-dlci 102

R2

int s0/0/1.102 point-to-point
ip add 10.1.2.2 255.255.255.252
frame-relay interface-dlci 201

Step 3: Verify full end-to-end connectivity.

Ping from PC to PC.

Task 8: Intentionally Break the PVC and Then Restore It

Step 1: Break the PVC using a different method than you used in Task 6.

Step 2: Restore the PVC.

Step 3: Verify full end-to-end connectivity.

Task 9: Document the Router Configurations

On each router, issue the show run command and capture the configurations.

Task 10: Clean Up

Erase the configurations and reload the routers. Disconnect and store the cabling. For PC hosts that are normally connected to other networks (such as the school LAN or to the Internet), reconnect the appropriate cabling and restore the TCP/IP settings.
