OSPF Packet Tracer Lab Configuration between 3 Routers

hi guys uh today we are going to establish the ospf routing between these three routers so i have already configured these ips to save the time so let's start with the upper spf routing so let's start with this router router r1 and now let's configure the izrp routing so for that first you need to go to the global config mode by this command now to configure the ospf router we have to issue this command router osp and here you need to enter the process id and you can use any number between one two six five five three five and it will create the ospf instance with that number and it may be different uh from router to router you can use any number it doesn't matter that like in eigrp you have to use the same autonomous number and keep in mind that this is not the autonomous number this is a process number so you can use it uh any process id now configure the network so in ospf we have to provide the all the network ids so for this the network id is 10 0 0 0 and for this network id is 11 0 0 0 and for this this is the 192.1 192.168.1.0 network and guys i have used slash24cidr for 192 networks and 100 1100 1200 uh this has slash 8c idr so subnet mask will be 255.000 for these networks and 192.168.1.0 the subnet mask will be triple to 5.0 so let's add it network 10.0.0 and now we have to enter the wildcard mask so for this [Music] on 100 we have to subtract 255 we have to subtract from 255.255.255.255. so when you subtract to the subnet mask then there will be 0.255.255.255. and now we have to enter the area number so enter the area and for area you can use any number between zero two four two nine four nine six seven two nine five and keep in mind that the area must be same for the every router that you want to perform osp routing right so i'm gonna choose the area number zero here now at the next network network 11.0.0 set network and the subnet mask will be like this it is the same now at the 192 network and for this wildcard mask will be this so here we have done with this router now here the networks are 192.168.2.0.10.0.0 so router ospf i'm going to use here 2 as the process id and network will be 10.0.0.0 0.255.255.255 and area will be the same guys another network is 192.168.2.0 192.168.2.0 so command is this and since it is finding the urgencies that's why it is showing these lines and also the process instance has been created now let's configure the spf routing on this router network 11.0.0.0 other network is what was the original for the network is 12.0 now let's perform the check the routing table so guys you can see all the neighbor network ids has been known by this router and all the directly connected network has also been known and you can see that 1910.00 12.0011.00 and 192.168.1.0 network has been found but it is not solving the 192.168.2.0 network now it is fine now let's ping the pcs guys let's wait for a little more guys now you can see that it is pinging now let's ping from this pc also so guys you can see that it is blinking and since the ospf routing has been established that is why it is pinging so thank you guys
