Practical Exercise OSPF and RIP Redistribution

Practical Exercises are designed to test your knowledge of the topics covered in this chapter. The Practical Exercise begins by giving you some information about a situation and then asks you to work through the solution on your own. The solution can be found at the end. Configure the network in Figure 4-8 for OSPF between the three routers named SanFran, Mel, and Simon. Configure the edge router named Sydney for RIP and ensure IP connectivity among all four routers. You must use only RIPv1 and...

CCIE Qualification Exam Test Format

The CCIE Routing and Switching qualification exam uses the typical certification test format with multiple-choice questions that have one or more correct answers per question. What makes some of questions more difficult on the exam is that more than five answer choices are listed for all or most questions. This reduces the effectiveness of eliminating obviously incorrect answers and choosing from the remaining answers. The topics tested include the following WAN (addressing, signaling, framing,...

Appendix D Ccie Preparation Sample Multiprotocol

This appendix is designed to assist you in your final preparation for the most widely sought after certification in the world today, CCIE (Routing and Switching). Today, many published books describe how to achieve CCIE, but in reality, no matter how many books you purchase, it all comes down to your level of hands-on experience. The strict nondisclosure agreement policed by Cisco ensures that candidates do not share any information about the lab content. Therefore, you'll know little about the...

Introduction to Enhanced Interior Gateway Routing Protocol EIGRP

Cisco Systems followed the development of IGRP with Enhanced IGRP. Enhanced IGRP combines the characteristics of distance-vector protocols and link-state protocols. EIGRP is commonly referred to as a hybrid routing protocol or an advanced distance-vector routing protocol. EIGRP can be used to route IP, IPX, and AppleTalk traffic. This chapter concentrates on IP routing with EIGRP. EIGRP uses distance-vector properties to determine the best path to a network, but it uses link-state properties...

Connecting Multiple OSPF Areas

An OSPF area is defined as a logical grouping of routers by a network administrator. OSPF routers in any area share the same topological view (also known as the OSPF database) of the network. The core reason that OSPF is configured in multiple areas is to reduce routing table sizes, which in turn reduces the topological database and CPU memory requirements on a router. OSPF is not just configured in one large area, so all routers share the same topological database. The use of multiple areas...

Distance Vector and Link State Routing Protocols

Now that you are aware of the routing methods available, this section looks at the two main types of routing methods that routers use to detect remote destinations dynamically. Distance vector protocols (a vector contains both distance and direction), such as RIP, determine the path to remote networks using hop count as the metric. A hop count is defined as the number of times a packet needs to pass through a router to reach a remote destination. For IP RIP, the maximum hop is 15. A hop count...

The Class B address 141.108.0.0 has been assigned to you for this task. You should ensure this address space is designed so that company growth allows you to use IP address space wisely to conserve it. Ensure summarization is possible with the three distribution routers. It is important that the IP addressing scheme is correctly laid out in a hierarchical fashion so that you can use summarization IP routing tables to keep them to a minimum. Start with the core of the network with a possible 20...

CCIE Lab Exam Test Format

Passing the qualification examination is the easier part of the CCIE exam journey. To pass the lab exam, your life needs to change dramatically, and you need to study on routers full time for at least three to six months. The good news is that the format of the lab examination has changed from two full days to one day only. You are no longer required to troubleshoot a network (regarded as the true method to test a CCIE's ability to restore a network back to full IP connectivity) you are now...
