So we're here in our final video for Basic Route Redistribution. We're trying desperately to get our OSPF routes into EIGRP. We've gone and we've typed the command here in our Redistribution Router, Redistribute OSPF 1 and we found out that, that means I have an infinite Metric and so Router 3's not even going to advertise these routes into EIGRP because, again, there so far away that you'll never get to them, so what's the point? Let's go back and look at this Redistribute Command in a little more detail. So we'll hit Up Arrow, Redistribute OSPF 1. We are going to have to specify a Metric, so let's do Metric, the first entry in our Metric calculation is Bandwidth, Metric and kilobytes per second. Now you'll recall all of the possible variables in EIGRP Metrics, Bandwidth, Delay, MTU et cetera. If you're going to specify all of these on this Metric line. Now in the real world you would actually sit down and you would run through all the variables of the EIGRP formula and you would say, well these are the actual values that I need to put in to distribute proper Metrics into EIGRP so that I'm not advertising this huge Metric that's just way out of line with everything else and therefore my routes will never be used. However for the Certification exam and for the labs, if you aren't told what Metric to use when you're distributing OSPF into EIGRP, you can use whatever numbers you want. In this case, we're going to just pull some numbers out of thin air. So the Bandwidth in kilobytes per second, we're going to say is 1,000. The next entry we have to give it is the EIGRP Delay Metric in ten microsecond units, we'll say 300. The next value we have to give it is the Reliability where 255 is 100 percent reliable, we'll go ahead and say 255. Next is the Load where 255 is 100 percent loaded, we'll say ten, because this network not really all that loaded down and the MTU of the path, again you can put whatever number you want in here. We're going to put 1500 just because it's mainly an Ethernet Network. And there we go, so now we've actually specified all of the variables that could go into the EIGRP Metric Calculation Formula. Bandwidth, Delay, Reliability, Load and MTU. So now we hit Enter and now we are actually Redistributing Routes into EIGRP. If we go up here to Router 1, we check the Routing Table, we now have external EIGRP routes for the networks that are being advertised via OSPF and you'll notice that the Administrative Distance is 170 for these routes and that's because these are external EIGRP routes. You can look more in depth into these routes, for example, if I were to do Show IP Route 10.20.4.0, there it is, it's now through EIGRP 1200, distance is 170, Metric is this big long number. It's an External, it's a Redistributing it via EIGRP 1200 so it knows it is a Redistributed EIGRP route. There's all of the Metrics put in. There's the Total Delay, in this case it's a little higher because the Delay got added in between Router 3 and Router 1 here, but if you'll look back at the other Metrics, there's the Load, there's the Reliability, there's the MTU and that was all advertised in via that Redistribute Command in Router 3. So now it's adventure time. Let's Ping from Router one to one of these Loopbacks that's up here on Router 4 and see if our packet makes it all the way across this Network Infrastructure to the other end. In this case, we're going to Ping 10.15.1.1, that's the Loopback up here on Router 4. So we'll go here on Router 1, Ping 10.15.1.1 and there we go. It's now going across the entire network through that Redistribution Router up to Router 4. Let's to a Trace Route just for fun and giggles. 10.15.1.1, you can see it goes through the only path available to us, down through here, across the Router 3, up to Router 5 and then up to Router 4 and it get's there, it's a really slow network but then again it's all emulated so it's not going to be the speediest in the world. And you verify that you are actually getting routes both directions. And so that my friends is the basics of Route Redistribution. Now in the next lab when we talk about Route Maps and Filters and Tagging, you, you've seen my advanced labs. I've got some really wild off the wall objectives in this lab. Then it gets really fun because again you can do all kinds of interesting things with these routes and especially once we start talking about Policy Routing, when you combine all of this stuff together, you can have absolute fine grain control over what data flows on, over what links on your network and that is indeed of the network engineer. For the time being that concludes our discussion of Basic Route Redistribution.
