Lab 30:
Configuring Frame Relay Multipoint Subinterfaces
Lab Objective:
The objective of this lab exercise is to configure Frame Relay multipoint subinterfaces, assign DLCIs to these subinterfaces and verify connectivity between two Frame Relay routers. By default, no subinterfaces are configured.
Lab Purpose:
Frame Relay multipoint subinterface configuration is a fundamental skill. Multipoint subinterfaces behave and act in the same manner as physical interfaces. They can be used between two or more endpoints, such as in a hub and spoke topology. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure Frame Relay multipoint subinterfaces.
Certification Level:
This lab is suitable for both CCENT and CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 6/10
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. Enable Cisco Frame Relay encapsulation on the Serial0/0 and 1/0 interfaces of routers R1 and R2.
Task 2:
Configure a multipoint subinterface S1/0.500 on R1 and assign this interface the IP address 192.168.7.1/30 and DLCI 111. Configure a multipoint subinterface S0/0.600 on R2 and assign this interface the IP address 192.168.7.2/30 and DLCI 222.
Task 3:
Verify Frame Relay mapping for these DLCIs and test connectivity between R1 and R2 by pinging between the two routers over the Frame Relay network.
