Overview In the previous part, we looked at some of the concepts behind switch operation. In this chapter, we will continue with the configuration and verification of the basic switch configuration, configure and verify port security on a switch and learn some other important concepts. Duplex settings As we mentioned in part 1 of this […]
Overview In this chapter, we will explore switching concepts and the basic configuration of a switch. We will discuss the switch’s operation, layer 2 and layer 3 switching as well as other concepts. We will conclude with the basic configuration of a switch and this will lead us into the discussion on VLANs. CSMA/CD We […]
Welcome to the world of LANS, in the previous couple of chapters, we learnt about routers and how they are used in the networking environments. In the next couple of chapters, we will learn about LANs and the main device we will use will be the SWITCH. The concepts we will learn will also tie […]
Overview In part 1 and part 2 of this chapter, we looked at the basic configuration of OSPF and further learnt more OSPF concepts such as redistributing the static routes and the metric, in part three, we looked at multi-area OSPF. In part four, we will look at OSPF and multi-access networks, we will conclude […]
Overview In part 1 and part 2 of this chapter, we looked at the concepts behind OSPF operation. In part three and the last part, which is part four, we will look at more advanced concepts in OSPF. In part three we will look at multi area OSPF. We will learn how it is different […]
Overview In the first part, we took a look at link state routing protocols and discussed how OSPF works. We also learnt how to configure OSPF. In part two of this chapter on OSPF, we will look at more concepts such as the OSPF metric, suppression of OSPF updates and redistributing the default route. OSPF […]
Overview Welcome to the world of OSPF (Open Shortest Path First) routing. This protocol was developed to replace RIP and it is a classless Link State routing protocol that uses areas so as to scale better. This chapter is divided into four parts since it is too broad. The concepts we will learn will be […]
Overview In part 1 of EIGRP, we explored some of the EIGRP concepts, we saw how it works and how routes are learnt, we also looked at the tables in EIGRP as well as the algorithm used and the different packet types. We also configured EIGRP and verified operation using the various show commands. in […]
Overview Welcome to the world of EIGRP. In this chapter, we will look at CISCO’s proprietary routing protocol which is EIGRP. In part 1, we will look at the foundation concepts into distance vector routing protocols operation. We will then look at the EIGRP concepts and get to know how it works as well as […]
Overview In the previous chapter, we looked at static routing. We saw how the router finds the best path to a network. We configured static routes and traffic was able to flow between two points. In this chapter, we will give an overview of dynamic routing protocols. We will define them and learn how they […]
