EIGRP Stub Sim

May 8th, 2014 digitaltut 796 comments

Question

TUT Corporation has just extended their business. R3 is the new router from which they can reach all Corporate subnets. In order to raise network stableness and lower the memory usage and broadband utilization to R3, TUT Corporation makes use of route summarization together with the EIGRP Stub Routing feature. Another network engineer is responsible for this solution. However, in the process of configuring EIGRP stub routing connectivity with the remote network devices off of R3 has been missing.

EIGRPStubSim

Presently TUT has configured EIGRP on all routers in the network R2, R3, and R4. Your duty is to find and solve the connectivity failure problem with the remote office router R3. You should then configure route summarization only to the distant office router R3 to complete the task after the problem has been solved.

The success of pings from R4 to the R3 LAN interface proves that the fault has been corrected and the R3 IP routing table only contains two 10.0.0.0 subnets.
