So let's continue configuring our Route Maps. So we've set up Access Lists that we're going to match in the Route Maps and so now in Global Config Mode we're going to set up the Route Map and then finally we're going Redistribute routes from EIGRP into ESPF using this Route Map. So it's kind of like those little Russian nesting dolls. You got to have A before you can do B before you can do C and so on and so forth. So let's set up Route Map, if we hit Question Mark, we have to give the Route Map a name or a Tag. It can be anything you want, it can be Bob or Sally or Suzie or it can actually reflect what the Route Map is used for. I recommend the latter so in this case we'll do EIGRP to OSPF. Now we hit the Question Mark and we are presented with either a Sequence Number to Insert Delete from the Route Map entry or we can just say Deny or Permit. Now if you just Enter you automatically get a Sequence Number of ten and each Sequence Number can only take a single action. Now I know the first time I set up Route Map, I just put or I tried to put all of my Match IP Address, this that and other and set this and set that and set the other and then when I exited, it only took the last command because you can match on multiple IP addresses but you can only do one Tag or one Set or anything like that against that Access List. In this case, we're going to give it a sequence number. So EIGRP to OSPF 10, oop, we need to actually say Permit and then the sequence number. And if you just hit Enter, it starts you off at 10 and you can build from there. So we'll do Route Map EIGRP to OSPF. We're permitting and the Sequence Number is ten. So now, now that we're in the Route Map configuration, we have the two basic options, we're going to be using which is Match and Set. Basically, you're going to say Permit Ten for this section of the Route List, Match this and once you Match this, then you Set that. So in this case, we're going to say Match and we can Match MPLS Labels, Metrics, Tags, all kinds of nice stuff. We'll be using Tag later on when we modify these Route Maps. So in this case we're going to Match on IP information and we're matching the IP address. So we'll Match IP Address and what Access List number we're wanting to match. So in this case we're Matching IP Access List 1 and if I recall that has to have a cost of 100 and a tag of ten. That works 10.10.1, it should have a cost of 100 and a tag of ten. So now we're going to Set and we can Set all kinds of things. We can Set BGP Attributes. We can set the Metrics, the Metrics Types, the MPLS Label if we're passing it out to an MPLS network. In this case, we're just going to set the Metric. So we're going to do Set Metric and the first value is the Bandwidth and Kilobytes per second or the Metric Value. Since at this point the Route Map doesn't know what Metric you're using, it can be just the cost or the bandwidth, and obviously the Bandwidth and Delay and Load and all that other stuff is for EIGRP and we'll see that when we set up the Route Map to go from EIGRP into OSPF. So in this case, we're going to set the Metric of 100 and we don't need to set any other Metric so we'll hit Enter. Then we'll also set Tag ten. So that's what we're going to do for the first set of networks in our Route Maps. We're going to Exit and then we'll go up here and we'll say Route Map EIGRP to OSPF Permit and we're going to say section 20 because we're going to take a different action on the next set of networks. So Permit 20, we're going to Match IP address 2 which is the 10.10.3 network, for the 10.10.3 network we will need to have a cost of 200 and a Tag of twenty. So Set Metric 200 Set Tag 20 Exit and go back up here and we'll go into Permit 30, Permit the next set of networks, should have a cost of 500 and a Tag of 55. And that is Access List 3. So we'll do Match IP Address three, Set Metric 500, Set Tag, is it 55? I have a bad memory and a Tag of 55, that's. Right. So Tag 55, we're going to Exit and now we're going to set up that Deny. Remember we're denying Access List 4, which is Permit 10.10.6.0. So in this case we're going to do Route Map, EIGRP to OSPF and we're going to Deny 40. In this case we're denying things that were matching. So in the Deny Mode, we'll go ahead and hit Question Mark and so you can actually set things when you're in Deny Mode. I don't know why you'd necessarily want to do that. In this case we're going to do Match IP Address four and that's it. We're just denying it outright, so we don't care what the Metric or the cost or the Tag or anything else is. We're not even distributing it over into OSPF. So now we'll exit from this and we're going to set the last one here which is Permit 50. And this is the last Permit Statement and so this will be the one that applies to all of the other routes that don't match any of the other statements. In this case, all other networks should have a cost of 250 and a Tag of 25. So we're going to Set Metric 250, Set Tag 25. And we'll Exit. Now we'll do a Show Run Section Route Map and there is our Route Map. We've got all of the Permit Statements, the Deny and this last one that effects everything else. So we're going to copy this out and put it in Notepad just so we can put it into Router 2 as well. We, we don't need that last line. And in the next video we're going to apply this to our Redistribution Command.
