Understand how frame-relay inverse arp dynamically learns IP addresses, and how static mappings or disabling the inverse arp affect mappings on both routers.
Learn how to configure OSPF on frame-relay networks by selecting appropriate network types for NBMA links, switching interfaces to broadcast or point-to-point, and using frame-relay map to establish neighbor adjacencies.
Configure frame relay point-to-point interfaces to replace multipoint links, assign IP addresses with DLC, and note that frame relay map cannot be used on point-to-point interfaces.
Repair the six-router frame-relay topology so every loopback can ping every other loopback using a TCL script, while preserving OSPF area assignments and interface IPs to achieve 100% success.
Resolve frame-relay connectivity by aligning OSPF areas and DR priority, establish adjacencies, verify with ping and TCL scripts, and adjust redistribution metrics to achieve full routing convergence.

Understanding and Configuring Frame-Relay is a challenging task. For example, how and when the inverse-ARP protocol works, how to configure the frame-relay switch, and how to solve issues with routing protocols in a frame-relay network are things that usually confuse CCNA and other Cisco certifications students, and therefore are needed to be clarified.
Although the detailed study of Frame-relay was removed from the curriculum of the CCNA and the other Cisco Certifications, understanding how it works and how to configure it is very useful to understand the mechanizes and the issues of NBMA or Non-Broadcast Multi-Access Networks in general.
This course contains five sections:
Course Introduction and Overview.
Basic Frame-Relay Configuration: in which I explained the configuration of end routers and frame-relay switch, how to configure the LMI Types, how to make the router ping itself, and how to understand the status of the PVCs.
Configuring Frame-Relay Multipoint sub-interfaces: in which I also explained the Inverse-ARP protocol.
Solving Issues with Routing protocols: in which I explained how to solve issues with EIGRP and OSPF routing protocols when Frame-Relay is configured, and how to configure the frame-relay point-to-point sub-interfaces.
Routing Lab: To further understand the previous section about solving Frame-Relay issues with routing protocols, I have added this lab about how to troubleshoot EIGRP and OSPF routing protocols in general.
Practice Test: in order for the students to check their understanding of the concepts and configurations explained in the course.
I hope that that you will find this course useful, and and that it will help you to understand how to configure Frame-Relay and to clarify its ambiguity.
