Scenario You are implementing EIGRP between the main office and branch offices. In Phase 1, you must implement and verify EIGRP configurations as mentioned in the topology. In Phase 2, your colleague is expected to do NAT and ISP configurations. Identity the issues that you are encountering during Phase 1 EIGRP implementation.

Router R1 connects the main office to the Internet and routers R2 and R3 are internal routers.

Routers Branch1 and Branch2 connect to router R2 in the main office.

Users from the Branch1 LAN network are expected to perform testing of the application that is hosted on the servers in Server farm1, before servers are available for production.

The GRE tunnel is configured between R3 and Branch1, and traffic between server farm 1 and Branch1 LAN network is routed through the GRE tunnel using static routes.

The link between Branch1 and Branch1 is used as a secondary path in the event of failure of the primary path to main office.

You have console access on R1, R2, R3, Branch1, and Branch2 devices. Use only


commands to troubleshoot the issues.


Enter IOS commands on the device to verify network operation and answer for multiple-choice questions.


Click on the device icon to gain access to the console of the router No console or enable passwords are required.

To access the multiple-choice questions, click on the numbered boxes on the left of the top panel.

There are


multiple questions with this task. Be sure to answer all four questions before selecting the Next button.

The traffic from Branch2 to the main office is using the secondary path instead of the primary path connected to R2. Which case of the issue is true?

The network was not advertised into EIGRP on Branch2.
The IP address was misconfigured between the Branch2 and R2 interfaces.
EIGRP packets were blocked by the inbound ACL on Branch2.
The primary path has more link delay configured then secondary path which causes EIGRP to choose the secondary path.
