2.2.2.4 Packet Tracer - Configuring IPv4 Static and Default Routes

- so welcome to this video on configuring ipv4 a static and default routes here we can see the accessing table of this a packet tracer activity coming to path to one here we can see exam internetwork and evaluate the need for static routing okay here they're given a couple of questions looking at the topology diagram how many networks are there in total yes here we can see that apology and we can see one two three four and five yes we can see total five Network so in this topology how many networks are directly connected to R 1 R 2 and R 3 routers okay here we can see the routers r1 r2 and r3 and coming to r1 we can see two networks are connected to r1 coming to r2 we can see 1 2 & 3 networks coming to r3 again we have two networks how many static routes are required by each router to reach networks that are not directly connected okay we will come to the topology here we can see for this r1 as I told we have a 2 directly connected and it works so it is unaware of three networks so that is 1 2 3 yeah here we can see 1 2 & 3 so we have to teach total 3 static networks on r1 and turn our 2 we can see 3 directly connected network and we have to configure two static route here we can see 1 and here we can see the second and coming to r3 it got to directly connected networks so we have to configure 3 static routes here we can see 1 or DC second here is third now we will come the next question test connectivity to the r2 and r3 lands by pinging PC - and PC three from pc1 why were you unsuccessful okay so when we ping from pc1 to pc2 and PC three it will be unsuccessful we will verify that first I am going to send a message instead of pinking I am going to send message from pc1 to pc2 got failed status going to send from pc1 to pc2 yes here also we got failed yes so it is unsuccessful from pc1 to pc2 and pc1 to pc2 trum this pc1 to pc2 or a pc 1 to p see 3 that's why it is unsuccessful we will go to packet to configure a static hundred default or routes we have a couple of questions here also configure recursive static routes on r1 what is a recursive static route yes so a recursive static route relays on a next hop router in order for packets to be sent it to its destination a recursive static route occurs the two routing table lookups the next question is so wide as a recursive static route require two routing table lookups yes so it must first look in the routing table for the destination network and then look up the exit interface or the direction of the network for the next to hope rotor yeah that's why it requires two routing table lookups now we will go to see configure a recursive static route to every network not directly connected to r1 in including the van link between r2 and r3 yes so we will do this configuration now now we will go through the router r1 okay yes enable configure terminal and we have to give IP route and here the network address is 1:7 2.30 1.0.0 space its subnet mask 255 dot 255 dot 255 dot 0 and its next hope etre so that is 170 2.30 1.1.1 93 and so we will go to the next IP route 170 2.30 1.1.1 96 and subnet mask is 255 over to 255 dot 255 dot 255 chefs 1 7 2.30 1.1.1 93 and the final route the third route IP route 170 2.30 1.1.1 28 and the subnet mask is 255 dot 255 dot 255 dot 192 yes on to the next hope at Rosie's 172 go to 131 dot obviously 1 to 193 193 yes yes configured static route on our one that is here we can see the and it works you know this network and is a second network and third network using the next to hoe patter so that is the IP address of this interface that is serial zeros are zero zero zero just connectivity to the r2 land and the pink the IP addresses of PC to and EPC three yes we are going to attest to the connectivity I am going to send the packet from here instead of doing pink I am going to send from I am going to delete these two failed okay from pc1 to pc2 we can see it is failed I am going to send from pc1 to pc2 yes it's failed yes it is unsuccessful obviously our one has route to r2 and r3 but this r3 and r2 do not have route back to r1 yes that's why it is unsuccessful so once we configure the I a static route on r2 and r3 obviously this connectivity will be a successful now we will go to a step to Y where are you unsuccessful yes that we already have seen configure or directly attach the static routes on our - yes now we are going to configure on r2 how does it directly attach the static route differ from a recursive static route yes so it directly attached to static route relays on its exit interface in order for a packets to be sent to its destination while the recursive static route uses the IP address of the next to hop router what we done on r1 configure a directly attached static route from r2 to every Network not directly connected yes so we are going to configure or on our two we have to configure this network our one here we can see the network so obviously the exit interface is this interface that is ZL 0 / 0 / is 0 and we have one more network here and the exit interface is obviously a serial 0 / 0 / 1 we will do the configuration on r2 coming to our to see la mode yes we are going to enable configure terminal here we are going to give you AI p route and we have to give the network our trust 170 2.30 1.1 dot 0 on to the subnet mask is 255 dot 255 dot 255 0 to 128 and the interface exit interface is serial as 0 / 0 / 0 and now we will give I pay route one more 170 2.30 1.1.1 28 yes and to the subnet - my subnet mask is 255 dot 255 dot 255 dot 192 and to the exit interfaces of serial 0 / 0 / 1 now we will go to B we have a number of questions here which command to only displays directly connected networks yes we have a show commander that is a show IP route connected so that we can see in which displays only directly connected networks which command only displays the static routes are listed in the routing table yes here also we can see this a show IP route static show command when viewing the entire routing table how can you distinguish between a directly attached static route and a directly connected network yeah so the static route has an S and an dat directly connected network has a C letters yes I wanted to show that they exactly attached and the static route how we will s distinguish came enable we have a show command show IP route yes here we can identify the letter C is 4 connected and s is for a static route now we will go to a step 3 configure a default route on our tree how does a default route differ from a regular static route yes so a default route also known as the Gateway of last resort is the network route used by a router when no other known route exists for a destination Network a static route is used to a road traffic to a specific network just now configure a default route on r3 so that every network not directly connected is reachable yes we will configure on r3 now coming to r3 yes enable configure terminal we will give I P route 0.0.0.0 and the destination prefix mask is 0.0.0.0 and the exit interface is a serial 0 / 0 / 1 now we'll go to be how is a static route displayed in the routing table okay we will verify that - coming to our three we will use the show command show IP route yes here we can see that using yes stop so this way this static route will be displayed in the routing table now we will go to step four document the command sephora fully specified rules right not a packet tracer does not currently support configuring fully specified static routes therefore these steps are documented the configuration for fully specified routes okay in this packet tracer this full a specifier routes will not be supported so explain a fully specified route which command provides a fully specifically static route from r3 to the r2 land okay we will see what is this a fully specified route a fully specified route is a static route that is configured with an exit interface and also the next to hope atrás so we have to see now here we fully specific static route from r3 to r2 land and r3 to the network between r2 and r1 and route from r3 to the r-1 land okay we will see these fully specified routes yes here we can see that fully specified routes IP route then we have to specify the network address subject to mask and to the exit interface also we specified the next hope atras we can see all these three commands for fully specified routes we are coming to step five you verify a static or Road configurations yes use the appropriate to show commands to verify car configurations which show commands can you use to verify that the static routes are configured correctly yes we can verify the routing table on each routers using the show command show IP route also we can use a show IP route a static we will do the verification now on each rotor coming to r1 yes enabled we have show IP route here we can see three static routes 1 2 & 3 also we can use separate to show IP route static separately so that we can see only the static route the same way I am going to verify on our to enable we have to give a show I P route yes here we can see a two static routes also we can use a show IP route static yes here we can see the two static route now we will come to the rotor r3 so IP route yes here we can see the default route now we will come to the last two paths to verify connectivity every device should now be able to pink every other device if not a review your static and default or road configurations yes we are going to verify from pc-1 pc2 pc3 each other instead of a ping command i am going to send a message using this symbol PDU i am going to send message from pc1 to pc2 yes it's successful I am going to send message from pc1 to pc2 it's successful and I am going to send from PC to to PC three yes it's successful well we configured ipv4 static and default routes successfully friends if you have any doubt regarding this ipv4 static and default routes you can comment below also your opinion suggestions are always welcome don't forget to subscribe the channel for future videos thank you bye bye
