Frame Relay Point to Point Configuration

/ ineedchris

Objective: This lab will provide the understanding of how to configure frame relay point-to-point interfaces on Cisco routers. Creating point-to-point frame relay links is a fundamental skill that network engineers need to be able to perform.

Purpose: Frame relay is a WAN technology used to send frames over virtual circuits that are locally identified as Data Link Connection Identifier (DLCI) numbers. In this lab we will use a preconfigured frame relay switch which can be found here. The purpose will be to configure three remote office routers to enable frame relay communication from the remote offices to each other office without the need of static routing. (This lab can be continued from the frame relay static config lab, you will just need to remove the ip addresses from the serial interfaces before beginning.)

Topology:p2p

Task 1: Use the proper cables to connect the ports as shown in the topology.

Task 2:  Configure host names on routers R1, R2, and R3 as shown in the topology.

Task 3:  Enable frame relay switching, configure the sub interfaces for point-to-point frame relay, and configure the sub interface IP addresses on each router in the topology.

Task 4: Verify configuration is working on all routers by pinging from R1 to R2 and R3.

Task 5:  Enable full mesh between all offices with a default ip route on R2 and R3.

Task 6: Verify full configuration is working on all routers and ping from every device to every other device.

 

ANSWER:

Task 1:
We need to use a crossover cables to connect two like devices.

Task 2:
