Serial Mark Routing Made Easy

Serial mark routing

[Music] hello everyone last day we have created a static Network and here today we will work with the dynamic network with the help of our IP routing information protocol so here are 2 device end devices and like this we will take 6n devices or 3 different network and we will create the network like previously we will create them with it so each and then we will add them through the routers through three routers here let's take this switch and connect them you and now we will just connect them with copper straight through well as they are different type of devices and if they were same type of devices we can we could connect them with the copper crossover well right beside it you can see it and here we will connect all the first eight hundred zero with the switches port you can give any of them because we don't need to configure the switch but we need to configure the router so we cannot connect just normally with the router we need to remember on which port we are connecting the switch so that we can add the same ip address as the same network you here also we are using copper straight over and we will connect routers it fastethernet 0 here you need to remember it because you will need to configure the router with the IP address that will be same as the end devices IP address that true we will create a network that have same IP address same Eid now we need to you can go to configuration and see that there are only two port we need more than 2 port to connect 3 router so for that we need to go to physical and then WI C 2 T and turn off the switch and take this inside this box and then turn on the switch again you can see that device is booting so let's just do this for the other Network you and after that WIC 2t again turn off the switch take it inside the box and turn the third switch on now everything is ok so we need to connect them as this is our serial port so we need to connect with serial where so here serial port 0 2 serial port 0 we are connecting with serial DT line here serial port 0 1 to this router serial port 0 and now we just need to rearrange them a bit and then configure them for configure them we need to give them IP address for that go to configuration and here we need to give the IP address that is why I was saying that you need to remember them where you are connecting the routers which put to which side here we will give this IP address 192 168 dot 1.1 here our I'm using a Class C IP address here as you can see and then turn on this router you can see the green signal so this line is on let's take a note so that we don't forget this IP address and now we need to have the same ip address a net ID in this whole network so we need to have the same net ID and the host ID will be different so we can add from 0 to 255 devices here we are using our second device and the Gateway default gateway will be the same as routers IP address because that is the only route from where the device can send and receive data as you can see from the figure let's go to the next PC and here also the host ID will be different and the default gateway will be same and then we need to do this for the other router and the PC too now let's just keep them note here so that we can remember them later here inside the configuration again we need to give a IP address here but this time this network is a different network it is a different router so we need to change the net ID - we cannot give 192 168 dot 1 we need to give it dot 2 3 4 5 in anything you want but you need to change the net ID here as it was our Class C IP address so you can change the first 24 bit as you want only the last 8 bit was for our host ID that is why we are giving different host ID here you this time - which in Giovanni ID 2.3 and then the host ID was not one for router and the PC will be no 203 you now all the things are configured only the these roots are actually do not configured yet so let's go back here again this was connected to our serial port zero so we need to give our IP address here and here we will use a Class A IP address you can use Class C IP address here too it doesn't matter I am just doing it so that I can remember where I put which ID and here you can say that this is a Class C IP address Class A IP address so the last 24 bit will be for our host ID you can add any of the host number there and here you can see the 18 routers configuration we will add it here first let's take the note here 10 dot 0 dot 0 dot an IP address for the second routers this side exactly like this here you can see that the net ID was same for all the different network of routers one site they are actually two different router but the route is actually in the same network because in between them there are no other routers there so this whole side will be under the same network so that is why we are giving the same net ID 10 and then the host ID dot 0 dot 0 dot and then the host ID will be different that will be 2 so we are giving the same net ID but the host ID is different because this is a and this is actually inside the same net they are for both from two different routers but we are using the same net ID you just need to watch them carefully when you give the IP address so let's give them this on this side you can see this is another site of two different router again so the net ID will be same but it will be different from the other route that we added before ok so now let's go to CF 4 0 and add it ok we added it already so let's go to router 2 and here we need to add 10 dot 0 dot 0 dot and then turn it on now this side serial port 0 1 and here will be 11.0 dot 0 dot 1 and another side will be 11.0 dot 0.2 now you will see that all the roots are actually turned on as you can see the green mark here okay and now we can just add the networks before sending the data in the static side as you have seen previously we need to give Network the mask and then the next hop but inside the routing information protocol here you can see only network is added we don't need to give the next hop or the root name here because this is actually dynamic routing so here it will actually find the hope by itself it does not we don't need to give them the hope name but we just need to give them the network and it will find the best path available for it to send the data from one device to another device or from our source to our destination it will find the path itself and it will also find the best path available in the static you cannot actually do this you will define the route and data will be sent from that route only if you delete one route the data will not be sent from the other route if even and there is the route outside the route that you have actually stated but in dynamic you will say that if we cut one route and the data will be still sent there by the other route even if we don't tell them that you can go from this way too it will configure it them itself and now you can see we are adding the network's from router one we can go to the network beside it and then the other route so we are adding those two and then we need to add the separate networks of the end devices or the PCs so we need to add them let's add it 192 168 . 2.0 you and in here 3.0 we can access any of the device from this network if we use dot zero and then its own network - we need to access its own devices - so here we are sending from PC zero to PC four okay let's go to our IP again the data just failed again okay yeah I just sent the network address only on the router one but router 2 and router 3 are not configured yet properly we did not add the network here so let's add the network from louder - we can go to 10 dot 0 dot 0 and 11 dot 0 dot 0 and then from router 2 we can access the network in the under the both the routers so from 3 dot sorry to 3.0 then 1.0 you here from the third router also we can access ten dot 0 dot 0 Levin then the first routers network in the second routers Network you now if we send from here to here okay it failed again okay I did not add the network of the routers network itself I need to add them too so 2.0 I did not add this network I only added the other routers network here but I need to add its own network too you now it can fail the first time because you can see that sometimes we can be in the device and it will take more than one minute to beam the device the first time it happens sometime okay now let's just see you and the data need to come back to the PC zero again and we failed again let's end it again undersea you okay this time it just yeah it was successful this time all is done but in this time we will add a different network here we will connect our router 1 and router 3 there will be another route and you can say that if we want to send from PC 0 to pc5 there will be a shorter route than the one given previously here now we can use this path from pc 0 2 pc 5 this will be actually easier than the one with the you know with another router so you so here IP address we are giving a different net ID here tool but it will be from the a-class IP address you Phil dot zero dot zero dot one two first routers CR put 0 1 and here to L dot 0 dot 0 dot - so this is our another network and let's add this network to all three of them here in the second router you can see that there is no connection with the second router to the root 12 but we will add these two you will see a bit later that it is actually necessary here let's add it to the first router and then go to the third router and add it as they are both connected with this root now as you can see that here is our network and if we were if we disconnect one well from this this one or another one then you will see that we can still send data from this PC to the second natural specie or third natural specie and this there is another way to send the data so if we want to access and devices from the second routers network and then we need to connect all the network inside this router to so we need to include 12.0.0 inside this second router and if we don't do it then we cannot send or receive data if we disconnect this so let's send the data from this PC to this PC and you will see that this time it will actually take the way that is shorter you there you can see that it did not go from to the previous way as it was going a bit ago but now it is actually taking the new route because it is the shortest path and the best path available you okay the successful so now let's even disconnect one where and see if it's the end the data if we can send the data let's disconnect this one and let's try to send data from our second routers network to third routers Network because there are no direct connection between these two router but it still can send data you will see let's send from PC to PC for as I have told before if we send the data first time it can actually create a bit problem as you can see it is coming back and then going back again there you can see the data is actually sent using the route available so we don't need to declare it like that we just need to include all the network available in one network in the routing table and we need to update the routing table every time we change something as one of the route is disconnected so the routing table is already updated that there is only route available is in the 12.0.0 so it is using that route this is the advantage of using our IP routing information protocol that's all for today and next time I will show you how to do the exact same network same this same network with a static routing and you will see that in that static routing we cannot actually the router will the data will not actually use the shortest path it will actually use the first network that we will provide them so that static routing is not actually the smartest one but our IP is actually really smart because it can actually understand the best path using hop count thank you for watching [Music] you [Music]
