Overview in the previous chapter, we looked at the role of redundancy in the network and the prevention of loops in redundant LANs using STP. In this chapter, we will look at how we can utilize the links between our switches more effectively even in a network that STP has blocked links on. We will […]
Overview In part 1 of this topic on STP, we looked at the STP concepts and discussed how STP helps in redundancy and loop prevention in LAN networks, in this second part, we will configure STP and as well as troubleshoot STP. Configuration of STP By default STP is on by default on CISCO switches, […]
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 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 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 […]
Overview In the previous chapter, we looked at the role of the OSI transport layer in communication. In this chapter, we will look at the network layer. We will discuss the addressing used, the functions, and the different network layer protocols, introduce IPv4, understand how packets move in the network and finally give an overview […]
