ccna routing switching cost.It is important that you know these 6 steps and how to plan IP addressing well. Many exam questions require you to perform this process, even multiple times to answer a question!6.3.1 Step 1: Determine Network and Host RequirementsIn this step, two things need to be done: . Determine how many hosts the largest network segment in the network contains or will contain; . Determine the maximum number of network segments the network will contain, which gives you an idea of how many subnets you will need. For established networks. you will need to do a lot of analysis. Of course, as far as the exam is concerned, Cisco will provide this information, and you will only need to performYou only need to perform these two tasks, calculating the number of hosts per segment and how many segments there are. Don't forget that when calculating the number of hosts, you need to consider each device connected to the segment, which includes PCs, servers, routers, switches, printers, and so on. Don't forget that segments can be logical, such as all ports of a switch or VLANs, which are discussed in Chapter 12. You even need to allow some room for expansion: add expansion space to the final number you calculate.To help with the remaining 5 steps, I will create a fictitious network that contains 14 segments, the largest of which contains 14 devices; in addition, a Class C network number (192.168.1.0) is assigned to this network o Now you can kA move on to step 2 o6.3.2 Step 2: Meet the Host and Network RequirementsIn step 2, you will use the following three formulas. . 2S>=number of subnets needed (where S is the number of subnet bits). 2H-2>= the maximum number of hosts contained in the segment (where H is the number of host bits). S + Hv = the total number of host bits for the specified address type.First, you need to determine how many host bits to borrow to create the subnet; second, you need to determine how many host bits are needed to meet the host count requirement; and finally, you need to add the number of bits borrowed to create the subnet to the number of host bits needed and make sure they do not exceed the default number of host bits for a Class A, Class B, or Class C network.
