Configuring 3 Router Network with Static Connections

hello everyone and welcome back to another coding chat with Zack today we're going to be configuring a three router network using static connections and in this network practice with a cisco packet tracer we will have three switches and 6n devices well let's go ahead and get started let's start by dragging out our in devices 2 4 5 & 6 next let's grab 3 switches and now let's get 3 routers now you can use your choice I will be using 2621 but use whichever feels comfortable to you and on this network we will be connecting our routers with serial connection however you have other choices though typically you will see that in your book or in lessons using serial connections so let's go ahead and make a couple quick changes we do that first by turning off the power grabbing the WI C 1 T and then turning the device back on now in this mil device we will actually need two serial connections turn that on and to our third device where we only need one ok great now let's go ahead and start connecting our network we do that first we will use the copper straight through and we will go from each n device to the switch now it's my personal preference to leave the first fast ethernet one to go to the router however that totally up to you it's just easier for me to keep track of things all right excellent next let's go ahead and add our serial connections and you can do that by either using the serial DCE the DTE connection or you can just use the automatically char choose this kind of crazy colored lightning bolt and do that just by connecting your devices notice we have serial connections with the clock on this serial 1 and this 0 0 serial connection alright great now we need to determine our addressing scheme so we do have five networks we have one two three four and five each one requiring their own network IP scheme so we're going to start right here we're going to do 192 168 2.0 Network we're going to make that a slash 30 and that will give us the network mask of 255 255 255 256 eped this will become a 3.0 slash 30 255 255 255 255 at just a little bit ok next we're going to follow a different convention we're going to say 10000 slash 24 which is 255 255 255 0 here we're going to do 30.0 0.0 / 1/4 to 5555 to the fact and here we're going to do a 50 Network / 24 once again okay excellent so now we have our five networks so now let's go ahead and start in figuring our end devices now this Fast Ethernet port right here FA 0 0 FA 0 0 FA 0 0 all three devices will individually be the default gateway for the devices in that network so let's click on here let's go to desktop IP configuration and we're going to use K 10 dot so the address will be 10.0 0.1 so we're going to just go ahead and make this 10 giving ourselves room notice it wants to use this subnet mask however we've already decided it's a 255 255 and our default will be 10.0.0.0 1 go to our next device this time 10.0.0.0 mask and our default gateway will be the same default gateway that we used on the last one right and we're just going to repeat this same process on each dot 1 this will be 11 okay great and to our 50 Network notice how keeping the same pattern across makes it easier for you as the network technician or administrator or the student to keep things in order ok great make sure I did that one yeah ok excellent next we want to test for the connectivity between end devices and we can do that quite simply by using this little envelope with the plus and all we do is click on here and here notice that was successful that was successful and that was successful excellent so now all of our in devices are communicating with each other that just leaves us with the router configuration so let's go ahead and start with the router 0 here go to the CLI type in in and then 4 after you hit enter type E in for enable and then config T for global configuration mode and now we're going to configure this router first thing you want to do is give it a host name and we will call this part 0 next we want to configure this fast ethernet port and that is int 4 interface F 0/0 now we need to give it the IP address high key address and that will be one ninth oops nope sorry about that that will be 10.0 0.1 255 255 255 0 so this is the IP address of that port and that's the mask next we want to go ahead and put those shut which will then change the state to up and notice it turned green and this is starting to communicate great now we can exit one time now let's do our serial port now notice that we do have a clock here so we need to set the clock rate as well so let's int s 0 / 0 first we'll do clock rate and we'll set that to 128 thousand books 1 2 min 0 next let's go ahead and set the IP address and now that will be 192 168 2.1 to 50 to 250 to 252 to two loops 255 255 255 to do - all right excellent now we also want to do our no shut here yeah notice that change stayed to down that's because we have to set this one up in order for both of them to communicate ok great now let's go to this next one hit no key in for enabled config T hostname r1 now let's set up our interface for the fast ethernet and we will set that IP address as 30.00 top one and that's a 255 255 255 dot 0 no shut light came on good now we will configure this which is still on this network exit one time and that is 0/0 IP address 192 168 2.2 255 255 255 255 no shut alright notice we have green now on both sides okay now let's configure our last router supports once again in for no enable config team we want to set this interface IP address and that's our 50 network and our network might ask is 255 255 255 0 no shut excellent now I did forget so let's go ahead and run right back over there take care that one real quick we do have to set up this serial 1 we do that 0 / 1 notice it does have a clock so we need to set the clock rate we'll set that again at 128 thousand now we need our IP address which is 192 168 3.1 no shut next all right now we can come back over here and configure that serial IP address 192 168 3.2 and once again putting a network mask no shut okay excellent now we have green lights all in all the locations and now we want to test for connectivity and notice I just click here to here and it failed so let's go ahead and ping let's go into here go to our command prompt and let's pain that far device which is 50 dot 0 dot 0 dot 11 and notice that the destination host is unreachable and that's because the routers know everything that's in their network but they do not know how to get from say here to here and this is where we need to set up a static route and so the first thing we need to do is we can come back to our first is type end and do show IP route and remember with the packet tracer command-line interface that's available in Cisco as with many command line interfaces you only need to type as much as needed to make the command understood so this network has only sees two networks the 10 Network and the 192 168 dot 2 network and that's it so what we need to do is configure it so that it sees the 30 the dot 3 0 and the 50 network and so we will do that by using the IP route command whoops we do need to get in to convey there we go and it is IP route and so we want to see starting with this 30 Network so we save 30.0 to 0.0 and that is a 255 255 255 0 so first we have the network the network mask and then the IP of the connection that allows us to get there which is this serial notice that is our first location and that IP was 192 168 2.2 now the next one that we want to get to is this networking so IP route 192 168 3.0 Network which is a 255 255 255 255 255 255 TDOT 0 dot 0 dot 0 255 255 255 dot 0 and 192 168 2.2 excellent so now if we type the end and we do show IP route we have the 10 30 50 the 192 168 - and the 192 168 3 networks all 5 of them excellent now let's go to this next one we will do the same thing in show IP route now here we have three it sees the 30 the 192 168 2 and the dot 3 networks but we still need for them to see this one and this one and we'll do that the same way going to global config mode with config T IP route now we want to see this so that's the 10.0.0.0 which is a 255 255 to get here to get to that we have this IP and that is 192 168 2.1 now we need to do the same thing with the 50 network and as you can see is we're just manually configuring all of the possible places that it needs to go to now here we need this is the port we need and that would be 192 168 3.2 and again in show type e route 10 whoops looks like I somehow miss the 50 right IP route 1 which was a 255 255 255 0 and that is 192 168 3.2 ok now we have entered that one more time and make sure we get it correct now finally when we add our last of ice here we go to show IP route we only have the 50 and the one 92.3 or 160 8.3 which is here so we need to do all three of the networks and we can start with 30 IP route 30.0 0.03 255 255 255 0 now we get there by this port 192 168 3.1 next we do IP route 192 168 dot 2.0 network which is a 255 255 255 - and we get there and by the same port and finally the dot 10 the 10 Network which is a 255 255 255 0 and we get there again by the same connection excellent now in the end we can go down here and do you show IP route 1030 50 excellent all right now we can test our network we can do that either by going into the ping the command prompt in pinging or we can use this the PDU and we can do that by just clicking here to here and notice that it failed which can happen on a network until they have made their connection so we'll try it once again now we get successful we can go from here to here successful from here to here 6 and again from here to here and of course if we want to do the other way we have that same ability and they're successful all the way across so when you see a failed attempt when you either tried to ping or you use the PDU here don't freak out try it again because many times it has not found the connection and so it has to try once or twice perfectly normal and if there are other issues you can then track it down by going one unit at a time well I hope you enjoyed this lesson if you have any questions leave them in the comment box if you like this video like and subscribe thank you very much and happy coding
