Load Balancing In this video we’re going to be talking about load balancing or load balancers. So what exactly is this? Well, let’s just take a look at one really quickly. Here is a load balancer device for $60,000. This is a Citrix load balancer. This is a hardware load balancer. And what this does is that it distributes loads cross web servers when you are managing a big web server farm. So to really understand what this really expensive device does is you have to understand what exactly are…

SLAAC Stateless Address AutoConfiguration You’ll learn about Slack SLAAC that’s stateless address auto configuration in IPV six. Our normal hosts, like usually our desktop computers, can be assigned their IPV six addresses through either static addressing where the administrator goes on. Each host individually and manually puts an IP address on there, or through Dhcpv six, which is equivalent to DHCP and IPV four, or through Slack, which there is no equivalent for in IPV four. Our DHCP servers, if we’re using DHCP, track the Mac address to IP address…

Unique Local and Link Local Addresses Learn about unique local and link local IPV six addresses. We’ll start off with unique local. Those are similar to IPV Four RFC 1918 private Addresses. So ten x one 7216 to one 7231 x and 192168 got x. The private addresses, they are not publicly reachable. They are assigned from the range FC zero double seven, and as always, hosts should be assigned 64 addresses. So that’s it for our unique local addresses, not so much to tell you about them, they’re pretty…

IPv6 Global Unicast Addresses Lab Demo In this lecture, you’ll learn how to configure IPV Six Global Unicast addresses with a lab demo. Just before I get into that, there’s another thing I want to tell you about, which is about broadcast and multicast in IPV Six. In IPV four, we can broadcast to all hosts using the at 255-25-5255 destination address routers. Don’t forward broadcast traffic by default, so that traffic will hit everything in the local subnet, but it won’t go beyond there. IPV Six does not support…

The IPv6 Address Format In this lecture, you’ll learn about the format of an IPV Six address. So you already know that it is 128 bits long compared to IPV Four’s 32 bit address. The IPV Six address is written as x colon, x colon x colon. So it’s a great big long address. But when you start working with IPV Six addresses, don’t get freaked out by the length of the address. It’s still just an IP address. So whether you’re working with IPV Four or IPV Six, everything…

Introduction This section, you will start learning about IPV Six, starting with how the addressing works. Now, if you’re an engineer working for a company, there’s actually quite a good chance that you won’t even be using IPV Six at all, particularly if you’re working for a small to medium sized company in a Western country. But you still need to know IPV Six. If you go work for a service provider or a larger company, or a company, maybe in another area, there’s a good chance that you will…

Dynamic NAT Lab Demo In this lecture you’ll see how to configure dynamic Nat with our lab demo. So this labs following on from the previous one where we configured static Nat, when we did that, we configured a static Nat entry for our host on the inside at ten dot o dot one, dot ten. And that was being Natted to the outside address of 203 dot dot 1133. In this lab, we’re going to configure another Nat rule to allow our PCs on the 100 two subnet to…

NAT Translations – Inside Local, Inside Global, Outside Local, Outside Global You’ll learn how to understand the output of the show IP net translation command. And strap yourself in for this one. It’s going to get a little bit hairy. If you’ve already watched a few lectures in a row, now is probably a good time to grab yourself a coffee before we get started with this one. You can see here we’ve got inside global, inside local, outside local and outside global. Now this is one of the most…

Introduction This section you’ll learn about Nat network address translation. We already spoke a bit earlier about why we have the need for nap, which is because of the exhaustion of the IPV four address space. That was a while back though, to the first lecture. Here I’ll give you a refresher with an overview of of that again. So once we’ve covered the need for it, we’ll get into the different types of Nat and how to actually configure and verify them. We’ll start off with static Nat, which…

Numbered ACLs Lab Demo In this lecture you’ll learn how to configure access control lists with a lab demo. So here’s the lab I’ve got to open in GNS three here and I’ve got a couple of routers, r One and R two. I’ve got PC One and PC Two are in the 100 one subnet and PC Three is in 100 two. I’ve already configured the routing. So if I console onto PC One and let’s try pinging R Two at 100 two, so ping ten two from PC…
