Frame Relay Part I

Overview In the previous chapter, we looked at PPP, we discussed how PPP worked and we said that it works at the data link layer, in this chapter, we will look at the final WAN topic in this course which is frame relay. In part 1, we will discuss the concepts behind frame relay operation […]

OSPF Part II

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 […]

OSPF Part I

The concepts we will learn will be […]

EIGRP part II

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 […]

Dynamic routing protocols

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 […]
