tailieunhanh - Lab Scenario 1 -- Frame Relay and OSPF

This lab is designed to be a build-to-specifications test. There are numerous issues that need to be addressed for this lab to work correctly. The lab is designed to illustrate some of the problems associated with NBMA networks and linkstate routing protocols such as OSPF. Although the lab specifications will require you to solve problems in ways that you will probably never see in a production network, you will find that the same problem can be solved more than one way, sometimes using layer 2 techniques and sometimes using layer 3 techniques. When you thoroughly understand each method, then you will be prepared for any. | CertificationZone Page 1 of21 Date of Issue 05-01-2000 by David Wolsefer Scenario 1 Frame Relay and OSPF Scenario 2 Troubleshooting Introduction Introduction Network Specifications Network Specifications The Starting Configs The Starting Configs Frame Switch R1 Hints R3 Solution Revealed R4 Grading Yourself Frame Switch Final Configurations Hints R1 Faults Revealed R3 Grading Yourself R4 Final Configurations R1 R3 R4 Lab Scenario 1 -- Frame Relay and OSPF Introduction This lab is designed to be a build-to-specifications test.

When you thoroughly understand each method then you will be prepared for any situation. Network Specifications When you are finished troubleshooting the network it should meet the following specifications 1. R1 must use a physical interface. 2. R3 must use a multipoint subinterface. 3. R4 must use a physical interface. 4. DO NOT use any PVCs or DLCIs except the ones indicated within the drawing. 5. Use OSPF exclusively as the routing protocol. Make all three routers members of area 0. You must use only the nonbroadcast network type. 6. R3 must always be the designated router. R1 and R4 should never be eligible to be the designated router. 7. R1 may ONLY use a single frame relay map statement. Hint you need a layer 3 solution here 8. R3 may NOT use frame-relay interface DLCI commands. 9. R4 must use a layer 2 technique to solve hub and spoke reachability problems. You may not use the same technique you used on R1. 10. Make sure you can ping every serial interface
