Lab 27:
Configuring IETF Frame Relay
The objective of this lab exercise is to enable and validate basic IETF Frame Relay on two routers using Serial interfaces. The default Frame Relay encapsulation type used by Cisco routers is Cisco Frame Relay encapsulation.
Lab Purpose:
IETF Frame Relay configuration and verification is a fundamental skill. Frame Relay is a Non Broadcast Multi Access technology that is commonly used in hub and spoke topologies. By default, Frame Relay will use Inverse ARP to map a remote IP address to a local DLCI. IETF Frame Relay encapsulation should be used when a non-Cisco Frame Relay switch is being used. When you configure IETF, it is also important to specify a non-Cisco LMI signaling type. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure and verify IETF Frame Relay encapsulation and non-Cisco LMI signaling.
Certification Level:
This lab is suitable for both CCENT and CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 4/10
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 15 minutes
| IMPORTANT NOTE:
In order to configure Frame Relay between two routers in your lab, you will need THREE routers! The first two routers will be regular routers, and the third will need to be configured as a Frame Relay switch. This can be any Cisco router that has at least two Serial interfaces. Please refer to Appendix A: Cabling and configuring a Frame Relay Switch For Two Routers for the appropriate configuration to issue on the Frame Relay switch. |
Lab Topology:
Please use the following topology to complete this lab exercise:
Task 1:
Configure the hostnames on routers R1 and R2 as illustrated in the topology. Configure IP addresses on R1 and R2 Serial0/0 interfaces as illustrated in the topology.
Task 2:
Enable IETF Frame Relay on router R1 and R2 Serial1/0 and 0/0 interfaces. In addition to that configure ANSI LMI signaling for the Frame Relay network. Verify IETF Frame Relay encapsulation on the interfaces.
Task 3:
Verify that the Frame Relay DLCIs have been received from the Frame Relay switch.
