i think this Ospf exercice is false

Level 1

my teacher gave us this exercice about Ospf  and i think it's full of falsifications and it's impossible to achieve what he wants ( sharing routing tables betwwen R1 R2 )

am i right ?

configuration in a text file below same for the packet tracer file.

Hello

I believe you are correct, If that is your only remit then its not clear enough to create a topology, I would go back and verify with your teacher, they must be a least a shared transit subnet between both rtrs to enable communication.

Hello,

 

the attached Packet Tracer file has devices with no configuration, are you sure you have sent the correct file ?

the point is the configuration doesn't make any sense R1 will have two ip addresses

1) 120.120.120.120/26 erea 120

2) 130.130.130.130/27 erea 130

 

 and R2 these two 

1) 140.140.140.140 /28 erea 0

2) 150.150.150.150 /29 erea 150

 

how can R1 communicate with R2 if they have diffrent addresses and ereas ???

 

 

 

Hello,

 

I think what they want you to do is configure HSRP on the routers, that way, both routers have interfaces in the same area. 

 

Hello,

 

in my experience, when a teacher gives you a task that seems odd, incomplete, or plain out wrong at first, they want you to configure stuff that is not explicitly mentioned. HSRP in this case. I configured your devices, review the attached file.

Hello

@Georg Pauwen 
The remit in the OP shows clearly no transit subnet between the two rtrs but does show separate ospf areas for each rtr.
The OP also states  "( sharing routing tables between R1 R2 )"  Now im not so sure what that actually is pertaining to but applying an FHRP like HSRP then those two routers will indeed have the same directed connected routes for all subnets in both rib tables. But won’t be learning anything from each other, in fact if you check the rib table I would assume you would see no ospf routes installed whatsoever just a populated topology DB of type 1-3 lsa’s
