Determining Requirements

Determining the network requirements is a part of the PDIOO Plan phase. Many types of requirements must be considered, including those that are related to technical and business issues. Any factors that might restrict the design must also be identified. In the case where an existing network is in place, these constraints can be related to what is already there and how the new network must be phased in to allow continuous operation. Technical requirements and restraints can include the following...

Figure 37 Route Summarization on a Nonoctet Boundary

192.168.3.64 28 192.163-3.60 28 -192.168.3.96 28 192.168.3-112 28 192.168.3.64 28 192.163-3.60 28 -192.168.3.96 28 192.168.3-112 28 Common Common Network bits Subnet bits To calculate the summary route, first write the subnet addresses in binary. Then, determine which network and subnet bits the addresses have in commonit can be helpful to draw a line at the end of the common bits. (Notice that the network portions of the addresses are all common, because they are all subnets of the same...

Hierarchical IP Address Design and Summarization

A hierarchical IP address design means that addresses are assigned in a hierarchical manner, rather than randomly. The telephone network provides a good analogy. This network is divided into countries, which in turn are divided into areas and local exchanges. Phone numbers are assigned based on location. For example, in North America, 10-digit phone numbers represent a 3-digit area code, a 3-digit central office code, and a 4-digit line number. So if you are in Europe and you want to call...

Routing Protocol Comparison

The following routing protocols can be used for IP Routing Information Protocol (RIP), versions 1 and 2 (RIPv1 and RIPv2) Open Shortest Path First (OSPF) Integrated Intermediate System-to-Intermediate System (IS-IS) Border Gateway Protocol (BGP) Version 4 (BGP4) Table 3-2 shows where these routing protocols fit in the various categories discussed earlier in this chapter. Each of the routing protocols is further described in the following sections. Later in this chapter, the IPv4 Routing...
