A common question many students have as they start their Cisco journey is whether or not they need to have a home lab. This is actually a great question and if you ask 10 different people you will probably get 10 different answers. But I will try to give you my perspective on it as […]
Overview Ipv6 is one of the most emerging technologies in networks. IPv4 addresses are almost exhausted and as such there is need for a new and better solution. In this chapter on IPv6, which is the last chapter of this CCNA training course we will look at the concepts behind this protocol, we will learn […]
Overview In the previous chapter, we learnt how NAT is important in helping devices in a network access the internet, we also looked at DHCP and how it helps in automatic ip configuration on hosts as well as the use of ACLs in filtering traffic in our networks. In this chapter, we will look at […]
Overview Ip addressing is a very important job network administrators have to accomplish, configuring ip addresses on routers, and other devices can be a challenge especially when the number of devices is many. In this chapter, we will discuss a solution to ip addressing of hosts which is DHCP. We will look at the concepts […]
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 […]
Introduction In the previous chapter, we discussed serial connections in the WAN, we also discussed the default data link encapsulation on CISCO switches which is HDLC. In this chapter, we will look at PPP, we will discuss some of its concepts, learn how to configure PPP as well as its authentication options and finally we […]
Introduction In the last chapter, we discussed some of the concepts that make the WAN work, we briefly described some of the protocols in the WAN. In this chapter, we will discuss serial links and the physical connections we use. We will then explore the default encapsulation on CISCO routers which is HDLC and finally […]
Overview In part 1 and 2 of this chapter, we focused on 802.1D STP, in this chapter, we continue with STP but we will focus on the different variations of STP mainly; PVSTP and RSTP. We will begin with the concepts that make these protocols different from 802.1D STP, then we will configure PVSTP and […]
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 the previous chapter, we looked at the various concepts that make switches work. In this chapter, we will look at VLANs. We will discuss what they are, how they work and advantages of using VLANs in our LAN networks. We will also configure VLANs in our LAN networks. What are VLANs VLANs (Virtual […]
