2.4.11 Packet Tracer - Modify Single Area OSPFv2

hi friends welcome to world in this video we are going to uh solve this packet tracer activity modify single area ospf v2 before coming to this activity furnace if you like to get any ccna version 7 online classes or any other project support you can contact our team using our website link you will get from the description below and also if you like to get these type of technical videos in future consider subscribing and also don't forget to enable that bell icon near the subscribe button so that you will get notification message whenever we upload a new video now coming back to this packet tracer activity here we can see our addressing table okay and we will go through the objectives in part one modify ospf default settings in part two verify connectivity scenario in this activity ospf is already configured and all entity devices currently have full connectivity we will modify the default ospf for routing configurations by changing the hello and dirt timers and adjusting the bandwidth of a link then we will verify that full connectivity is restored for all entity devices we will go one by one part one modify ospf default settings step 1 test connectivity between all anti-devices before modifying the ospf settings verify that all pcs can ping the web server and each other okay we will test the connectivity uh we will take our addressing table uh we will get the ip address of pc2 and we will ping from pc1 we'll go to command prompt and here we will give the ping command then the ip address of pc2 we may get one or two request timed out and then we will get the replies yeah then we will get the ip address of pc3 ping pc3 okay then we will get the iep address of this web server here we can see our web server we will ping from pc1 to this web server we may get one request timed out yep it's working step two adjust the hello and dead timers between r1 and r2 enter the following commands on r1 we have to go to interface the serial 0 0 then we will change this um hello interval and that interval ip ospf hello interval 15 then i p ospf at that interval 60. coming to our topology here we can see that interface uh serial 0 0 0 which is connecting to this rotor r2 so we will go to r1 and we will give this command enable conf t then we will go to that interface serial 0 0 0 and we will set ip ospf hello interval 15 okay also we will set ip ospf dead interval 60 after a short period of time the ospf connection with r2 will fail as shown in the router output so we get this message neighbor down dead timer exped okay we will see that here yes here we get that message how we can rectify this both side of the connection need to have the same timer values in order for the adjacency to be maintained identify the interface on r2 that is connected to r1 then adjust the timers on the r2 interface to match the settings on r1 yes we have to configure the same hello interval and there's a dead interval on the other side of the link we will verify that interface it's a serial 0 0 0 we will go to that router and configure it and here also we can see we get that message enable conf t we will go to interface serial 0 0 0 and we will set that ip ospf hello interval 15 also we will set ip ospf dead interval 60 after a brief period of time you should see a status message that indicates that the ospf adjacency has been re-established so we have to get this message loading done yeah here we get that loading done even we can verify in r1 and here we can see neighbor and loading to full loading done now we will go to step three adjust the bandwidth settings on r1 trace the path between pc1 and the web server located at 64.100.1.2 notice that the path from pc1 to this uh server is routed through r2 ospf prefers the lower cost path yes that is correct so we will give this a tracer command i will go to pc1 command prompt will a tracer to this server and we can see it goes to default gateway then we can see it goes to 172.16.3.2 we will identify the iep address here we can see the first iep address 172.16.1.1 this is the default gateway of this pc1 that is the ip address of this interface g 0 slash 0 in this router r1 we can verify that i will give exit or we can give end so ip interface brief and we will see the ip address here g0 0 here we can see 172 16 1.1 yes it's correct the next is 172 16 3.2 we'll go to r2 and we'll verify it end show ip interface brief and here we can see that ip address 172 16 3.2 the ip address of this interface serial 0 0 0 in this router r2 okay then we can see it goes to this 209.165.200.226 so maybe that will be inside this internet and here they specified that uh network address let me verify it 209 165 226 yeah maybe they given to 25 here and the other side they given to 26 that's fine and finally it reaches to this server we will see this in simulation mode so that it will be more clear so just i will click on simulator simulation and here we can see show all or none just we will click edit filters we will go give only this icmp then close this also i will close this then i will maximize and delete this okay now i will send a packet add a simple pdu from pc one uh to this web server so that we can view this packet path we'll click capture and forward it goes to s1 then it goes to r1 then we can see it goes to r2 then to this internet then it goes to web server we identified the router from pc1 to this web server on the r1 serial 0 0 interface set the bandwidth to 64 kb per seconds this does not change the actual port speed only the metric that the ospf process on r1 will use to calculate best routes so we are going to change the bandwidth of the interface serial 0 0 0 in this router r1 we will go to r1 and we will change the bandwidth config we will go to that interface that is serial 0 0 0 and we will set that bandwidth 64. trace the path between pc1 and the web server located at 64.100.1.2 notice that the path from pc one to this web server is redirected through r3 ospf prefers the lower cost path okay we will check that we have to give this a try set command again in this uh pc one we'll go to pc1 command prompt and press up arrow from keyboard so that we'll get the previous command we given and we can see the details here we can see the default gateway of this pc one then we can see this ip address the ip address of this router r3 then the ip address of r2 then it goes to the internet then to the server we can see this in simulation so it will be more clear let me click on simulation and here we selected only icmp we will choose this add a symbol pdu then send from pc1 to this web server and we'll click on capture then forward it goes to s1 then it goes to r1 and here we can see it goes to r3 then r2 then to the internet and finally to the web server okay finally verify connectivity verify that all pcs can ping the web server and each other okay we will ping from pc1 to pc2 pc1 to pc3 and pc1 to web server okay we'll go to command prompt i will press up arrow from keyboard so that we can ping 172 16 2.2 so we are pinging to our pc2 then we will ping to our pc3 192.168.1.2 that's correct then we will ping to this web server it's here yeah it's working okay that's all in this activity modify single area ospf v2 here we can see our completion status it's a hundred percent now dear friends if you have any doubt any suggestions regarding this packer tracer activity uh please comment below or you can contact our team using our website link you will get from the description below and if you like our video give a thumb and share with all your friends stay tuned and we will meet again with the next video thank you
