GNS3 Lab & Exercise: EIGRP & OSPF Route ManipulationWritten by LBSources from http://www.gns3-labs.com on June 26th, 2010 | 3 Comments
So here is another lab I put together based on some studies and reading recently. I basically put together the scenario, so if it’s lacking conveying the scenario in a professional manner, I apologize
This is basically a simple route redistribution and route manipulation lab. Simple, but requires a few steps that will test your ability to adapt to an already deployed network while implementing a new routing protocol.
Hope you enjoy!
Company Tapan wants to enable EIGRP AS 1 on R1, R2 and R3. They would like to connectivity between all routers and subnets with the exception of the loopback interface on R1. R3 should NOT be able to communicate with R1′s Loopback interface. Unfortunately Tapan cannot eliminate advertisement of R1′s Loopback interface due to other network dependecies on the other side of R1 (unseen here).
Additionally Tapan is planning to segment the networks between R1, R2 and R3 using OSPF. They would like 2 OSPF areas. The OSPF area between R1 and R2 will be the core (Area 0). The area between R2 and R3 will be Area 1.
Tapan has determined that they’d like to reach R1′s loopback via OPSF. Tapan would like that R1′s Loopback interface be reachable via OSPF ONLY.
Tapan has hired you as the network consultant to configure their required network scenario.
When R3 can communicate with R1′s Loopback using the scenario above, your job is done.
Because R1 is a bit inflexible, the IP and EIGRP configuration is already in place and CANNOT be changed. Only OSPF can be configured on R1 to R2.
Routers Used: 3640
Feature of Topology: EIGRP, OSPF, Route Redistribution

I perform all of these labs on my own using my own knowledge and experience (warning and disclaimer). They may very well be implemented differently than a method you might choose. So long as it meets the requirements and works, essentially it’s acceptable (In my feeble opinion). But if you notice a terribly or complicated method used by me to achieve the goals and you feel yours is much easier, makes sense or is the standard; please do share – I’m always open to learning
