200-301 network simulator

200-301 network simulator.Part 2 of this book focuses less on LAN topics from Part 1 and more on IPv4 routing aspects. The ICND1 book (and exam) will introduce a lot of detailed information on IPv4 routing - concepts, full subnetting algorithms, and implementation details on routers. Now, Part 2 of the book will go into more depth. This section will review IPv4 routing topics in ICND1, but for now, let's look at troubleshooting in IPv4 interconnected networks, which will be discussed in detail in Chapters 4 and 5. The last two chapters of this section will add some topics that are not related to IPv4 for ICND1. Chapter 6 introduces the concept of redundant default routers, and Chapter 7 discusses how to use IPv4 to create private network connections on the Internet.Part 2 IPv4 RoutingChapter 4 Part 1 Troubleshooting IPv4 Routing Chapter 5 Part 2 Troubleshooting IPv4 Routing Chapter 6 Creating Redundant First-Hop Routers :Chapter 7 Virtual Private Networks Part 2 Exam ReviewTroubleshooting Identifying and Correcting Common Network Problems Troubleshooting and Resolving Routing Problems Enabling RoutingRouting tables are correct Correcting path selectionChapter 4.Part 1 Troubleshooting IPv4 RoutingIPv4 routing requires mutual coordination between hosts and routers. First, the host creates IPv4 packets and sends them to one of the nearby routers (the host's default router or default gateway). The router then makes routing decisions to determine where to forward the IPv4 packets and sends the packets to the next physical link. This process is repeated for each router that receives an IPv4 packet until the packet finally arrives on the specified host.This chapter will focus on how to troubleshoot IPv4 routes. This chapter will focus on packet forwarding (i.e., the data platform for IPv4). For the most part, this chapter will not discuss the data link layer and physical layer issues discussed in Part I (LAN) and Part 4 (WAN), but more on the network layer functions of IP routing. This chapter will also not discuss IPv4 control platform topics, particularly with respect to IP routing protocols, which will be discussed in Part III (IPv4 Routing Protocols) of the book.This chapter will review IPv4 routing topics throughout to help you learn about IPv4 routing troubleshooting. Cisco places most IPv4 routing concepts, configuration, and verification topics on the CCNA-wide ICND1 exam, but places the troubleshooting aspects related to these topics on the ICND2 portion of the CCNA. Therefore, this book has a dedicated chapter related to IPv4 troubleshooting, which will help you understand some of the details of this knowledge, and this chapter will discuss IPv4 review from beginning to end.
