To be able to understand and apply the concepts in this chapter, you should be familiar with addressing and routing concepts for TCP/IP networks. Although the addressing mechanisms discussed in this chapter are relatively straightforward, you should have some background in IP addressing; thus, a good addressing reference is provided here. In addition, you should have some background in routing protocols, particularly Routing Information Protocol (RIP)/RIP version 2 (RIPv2), Open Shortest Path First (OSPF), and Border Gateway Protocol version 4 (BGP4). Some recommended sources of information include:

The host requirements and router requirements RFC and STD listed are heavy reading but thoroughly describe the vital characteristics of hosts and routers on IP networks.
