So we're going to discuss Routing in IPv6 and we're eventually going to set up RIPng and RIPng is, is basically the same old RIP that you've grown to know and love in the IPv4 world or grown to know and hate depending on you experience with it. It still uses UDP Port 521, it still uses Hop Count. It still sends Route Updates every 30 seconds, it still does all this but it just uses IPv6 addresses instead of IPv4 addresses. Honestly, this is one protocol that I really wish would, would die because no one that I know uses RIP for anything unless you're talking to some consumer level device or some brain dead device that only understands RIP, doesn't understand OSPF or EIGRP and, and honestly if it doesn't understand any major routing protocols like OSPF or EIGRP or BGP, why are you trying to use it in an enterprise? But I, I digress, I'm sure there's reasons for having RIP in IPv6. However first we're going to set up a Static Route, just so I can Ping from Router 4 down to this address, this ::1 address on the 2001:2 network. And the reason I'm going to do that is just to introduce the concept and show you that you can set Static Routes with IPv6 just like you can with IPv4 and in fact, I think it's a little simpler to set it up on IPv6. So we'll go here to Router 4 and we're already in Enable Mode so we'll go to Config T, we'll do IPv6 Route just like the regular Route Command and if hit Question Mark, it wants to know what network we're trying to get to and where to go. It's just like with a regular Route Command. So we're trying to get to Network 2001:2:: slash 64 and our next hop is, if we check out here is 2001:3::2. So 2001:3::2 slash 64, opps I forgot you don't have to specify the, the Mask there, just like you wouldn't have to, on the, a regular Route Command and you can set the Administrative Distance here, we're not going to. So IPv6 Route that. Now if we do Show IPv6 Route we now have a Static Route to that network via that host. So now if we were to Ping IPv6 2001:2::1, well it failed and for the same reason that it would fail on IPv4 is because Router 2 does not have a route to get back. So let's Ping the ::2 address just to prove that this works. So we'll do :2 and now that's successful. So it's getting to this interface on this router so we know that this works. I won't go through the process of setting up a Static Route on Router 2 because we're about to set up a RIP and this whole problem will just kind of go away once we do. So let's go ahead and Undo this Static Route. So we'll go up here and copy out the command that I ran, copy out all of it which will help. And then we'll go into Config T and we'll do No and that command and I think we only need the first half of this, yes. So if we do Show IPv6 Route, we now no longer have that Static Route in place. So we'll go and set up IPv6 RIP on all four of these routers it will take a minute because it's pretty simple to set up, a lot simpler than setting up RIP or at least just a simple setting of RIP under IPv4. So Config T, we have Unicast Routing already enabled so we don't have to do that. We'll do Interface Fast Ethernet 0 slash 0. And we just do IPv6 and here's all the commands we can type under here. We'll, we're going to do RIP so we'll do IPv6 RIP. We have to give it a string which identifies the Routing Process and it can be anything you want and it does not have to match on any of the routers so in this case we'll do IPv6 RIP, R1 or actually we'll just say Route 1 and then we just do Enable. And that enables IPv6 Processing on that interface. Like I said pretty simple, so let's just copy this command out because we're going to be using it a lot I have a feeling. Go over to Router 3, clear out that command there, we'll do Interface Fast Ethernet 0 slash 0. We'll just Paste that Command in there and then we'll do Interface Serial 0 slash 0, Up Arrow twice, Run that Command. Router 2 the same thing, Config T, Interface Fast Ethernet 0 slash 0, Paste that Command in there. Oop got to do Interface Serial 0 slash 0, Paste that Command in there again and finally over to Router 1. Config T, Interface Fast Ethernet 0 slash 0, Paste that Command in and Control Z. So now if we go back out to Router 4, we do Show IPv6 Route, we have routes in our Routing Table for the 2001:1 2 and 3 networks all learned via RIP or that, technically that 2001:3 is learned via connected, but the other two are learned via RIP. The same thing for the other routers. So now the big test all the way from Router 4 all the way over to Router 1. So we'll do Ping IPv6 2001:1::1. We get packets back and if we do Trace IPv6 to the same address, 2001:1::1 we get Trace Routes just like we would with IPv4. We get the same thing back. So as you can see, it's not really all that scary despite those mile long addresses and that's pretty much it. We've set up Routing on IPv6, we've talked about the address spaces and this concludes our discussion of IPv6.
