ccna 1 and 2.To complete this task, you will need to use the PCPT software to answer the review questions in that section of the book. For help on how to use the PCPT software to display only the review questions for that section, please refer to the Introduction to this book section "How to view only the review questions for that section by section". gg-review exam pointsGo through the section again with the icon labeled "Exam Essentials". If you are not sure what you are looking at, take some time to reread the section. Creating the OSPF and EIGRP Root Cause Mind MapChapter 11, "Troubleshooting IPv4 Routing Protocols," focuses on troubleshooting problems with Open Shortest Path First (OSPF) and Enhanced Interior Gateway Routing Protocol (EIGRP), especially as they relate to interface and neighbor relationships.For the first "partial review" mind map, start by identifying all the conditions that you can think of that fail or cause problems in an IPv4 network and, by extension, make all routing protocols inoperable (such as those discussed earlier in the book). In other words, think about where the root causes are. Then organize them into a mind map.To organize into a mind map, start by listing what's in your head. Next, once you have identified a few related root causes, group them into a random category. There is no right or wrong form of organization as far as root causes are concerned. For example, you might notice root causes such as a LAN interface that is closed on a router or mismatched IP addresses (not on the same subnet). You might next categorize these causes as "IP connectivity on the same subnet" or "pingable to the same subnet," as in Figure P3-1Part 3 Pre-test Review 245The following is shown.

Create a command mind map, as you have done in many other sections of the review. The first level of organization should be OSPF vs EIGRP, followed by configuration vs authentication. In the middle of the validation area fields, further organize these commands related to interfaces, neighbors, topology maps, and routing as in Chapter 10, "IPV4EIGRP".
