1. OVerlapping VPN Overlapping VPN. Now, in this section I’m going to explain you how the overlapping VPNs are going to work. Let me just give you a basic idea what exactly overlapping VPN. So if you just get back to the previous videos, what we have learned, we have seen some of the basic […]

1. Multicasting – Introduction In this video we will try to understand what is multicasting and what are the benefits we get with a multicast instead of using a broadcast or unicast. Now, multicasting is a method of sending one single stream to multiple destinations. Like if you take an example, there is some a […]

4. Dense Mode Configuration Now in this video we’ll see the configuration of IP pin dense mode. Now, before we go ahead, let’s try to quickly revise some of the dense mode concepts. Now, dense mode uses something called flood and prune behavior where all the routers initially flood out the multicast traffic or the […]

1. IGMP Protocol and Versions Now, in this video, our main focus will be on IGMP protocol. But before we go ahead with IGMP, let’s quickly summarize what we discussed in the previous sections. Let’s say there is a multicast server sending a multicast traffic to some of the receivers on the remote network. Now, […]

4. Class Based Weighted Fair Queing Now, in this video we’ll discuss about class based weighted failure queen. Now, class base weighted fail queen is an extension to the default quing mechanism which we used in our previous sections, weighted fail queen. And here in case of class base, we are going to define our […]

1. Queuing Basics Now, this is the first introduction video on the condition management. Now in this video we’ll see some of the basic reasons for congestion, when and which scenarios the condition will occur and what are the different king mechanisms we can use to overcome this condition process. Now, we have different mechanisms, […]

3. CBWRED – Configuration Now in this video we’ll see the configuration of class based weighted trade based on the IP presence values. Now I have designed a small lap where we are going to see how to configure the weighted rate based on the IP presence values here. Now here I’m going to assume […]

1. Congestion Avoidance Now, in this section we’ll talk about congestion avoidance mechanism used on the Cisco routers. Now, before we go ahead, we’ll try to quickly revise some of the basic wing mechanisms which we have discussed in our previous sections. And then we’ll try to understand what is exactly tail drop and what […]

1. Classification & Marking Now, in this video we’ll see some basic introduction to the classification and the marketing. Classification and a marking is a basic feature of the quality of service. Now, if there is classification is a method of differentiating the traffic in different classes. Like let’s say you have some voice traffic […]

1. Create an HA Cluster in vSphere 7 In this video, I’ll demonstrate how to configure High Availability in Vsphere seven. And one of the important things that I want to note right up front is that we’re creating an Ha cluster. This is not Vcenter. High availability. That’s a completely different feature. Vsphere high […]
