  SIMULATION

  EIGRP Stub Sim

  

  By increasing the first distant office, JS manufactures has extended their business. They configured the remote office router (R3) from which they can reach all Corporate subnets. In order to raise network stableness and lower the memory

  usage and broadband utilization to R3, JS manufactures makes use of route summarization together with the EIGRP Stub Routing feature. Another network engineer is responsible for the implementing of this solution. However, in the process

  of configuring EIGRP stub routing connectivity with the remote network devices off of R3 has been missing.

  Presently JS 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.

  Correct Answer. Check the answer below
  Check the answer below

  Notice that R3 is configured as a stub receive-only router. The receive-only keyword will restrict the router from sharing any of its routes with any other router in that EIGRP autonomous system. This keyword will also prevent any type of route

  from being sent.

  Therefore, we will remove this command and replace it with the eigrp stub command:

  R3#configure terminalR3(config)#router eigrp 123R3(config-router)#no eigrp stub receive-onlyR3(config-router)#eigrp stubR3(config-router)#end

  Because we want the routing table of R3 only have 2 subnets so we have to summary sub-networks at the interface which is connected with R3, the s0/0 interface of R4.

  R4>enable R4#configure terminalR4(config)#interface s0/0R4(config-if)#ip summary-address eigrp 123 10.2.0.0 255.255.0.0

  Now we jump back to R3 and use the show ip route command to verify the effect But in your real exam, if you see the line “10.0.0.0/8 is a summary,….Null0” then you need to summary using the network 10.0.0.0/8 with the command “ip summary-address eigrp 123 10.0.0.0 255.0.0.0” . This configuration is less optimize than the first but it summaries into 2 subnets as the question requires (maybe you will not see this case, don't worry!).
