So we're setting up the second leg of our Redistribution. We're Redistributing from OSPF into EIGRP here on Router 1. We've set up our Route Map and so now let's go into EIGRP and Redistribute on this guy. So Router EIGRP 1, 2, 3, 4. We'll Redistribute OSPF Process 1. We're going to say Route Map and we're going to say OSPF to EIGRP and see if there's any other commands here and there's not. We are Matching in the, in the Route Map. So we'll hit Enter there. Let's see if that did it. Go over here to Corp 1, do Show IP Route and look at that. We're getting external EIGRP routes for the three networks down here exactly as we'd expect. We're getting them from 10.100.1.2 which is Router 1 and we're only getting them from that router because we haven't set up the Redistribution on Router 2 yet. Once we do that, we should start getting Load Balanced routes. But let's look at one of these external routes. So we'll do Show IP Route 192.168.12.0. There's the Route Tag we've got set, there's the Load, the Reliability, there's the Delay. It added some to the Delay because it had to cross these Serial Links here. There's the minimum Bandwidth so it's Redistributing using the Route Map that we set up into EIGRP. So we'll do a Show, we're actually going to have to do, Do because we're not in Config Mode. So we'll Do Show Run slash Section Route Map. And we're going to pull out this Route Map from this guy, oh there's no Route Map on Corp 1 what am I thinking? We'll Do Show Run Section Route Map and there's our Route Map for OSPF to EIGRP. You'll notice that it gave us a Sequence Number of ten, even though we didn't specify one. But that's the one by default, so we'll copy that out, move over here to Router 2, set this up. We'll do Exit, we'll go into Router EIGRP 1234, Redistribute OSPF one Route Map OSPF to EIGRP and hit Enter. Now if we go up to Corp 1 we should be getting Load Balanced routes from both routers and we are because both of the routes have the same Metric because they're all coming from the same place with the same Route Map having the same Metric applied to them, no matter where they actually come from down here. So now we have completely completed the first three objectives. We've set up the routing protocol, we've Redistributed from EIGRP into OSPF and from OSPF into EIGRP using the parameters that are specified here. Now to number four, filter the route updates using predefined Tags to prevent Route Update Loops. Now right now we don't have any Route Update Loops, we can go to both routers and we can do Show IP Route and we're not getting multiple copies of the same routes because they're going back and forth between the routing protocols. However, that may not always be the case. OSPF and EIGRP are generally pretty good about not creating a loop like that, but if you get some of the routing protocols that may not be as intelligent as some of these like EIGRP or RIP then you may have to actually use these Tags to filter the Route Updates. And besides it's, it's good practice to do and it's a, it's a realistic scenario. So let's think about this here on our graphic. We are Redistributing and we'll take the easier of the two, which is from OSPF into EIGRP. So anything that's coming from OSPF into EIGRP is being Tagged with a route of 500. So that means if there's a route that's over here in the EIGRP routing domain and it has a Tag of 500 on it, then we automatically know that it was Redistributed from OSPF and so once it goes back into OSPF we need to filter out any routes that have this Tag of 500. So this is where we modify our Route Maps to add this line in there right above the Permit All. So let's go over here to our 1 and there is our Route Map, it just happens to be up there. So here it is from OSPF into EIGRP so we've got a Permit ten here. So let's go into Config Mode and let's add a Deny Statement before that Permit, because obviously we're permitting everything at this point. So we'll do Config T, we'll do Route Map OSPF to EIGRP. We'll do Deny 5 because we want to deny any routes that match this Tag before we permit everything here. So we've got Deny 5, we're going to Match, if I can type, we're going to Match Tag 500. And that's it. We Exit from here and if we look at the Route Map, I'll Exit and do a Show Run Section Route Map, we now see that we have a Deny 5 up here at the beginning so if it matches Tag 500 it's going to deny it, otherwise it's going to fall into this Route Map OSPF to EIGRP and it's going to permit it and Set the Metric such as this. So we'll pick this up again in the next video. We'll modify the other Route Map and we'll do the same thing over on our R2 and verify that we didn't break our routing in the next video.
