A. It is complete as written.

B. It should include a task to configure EIGRP multipath equal to 2 on R1 and R4.

C. It should inc lude a task to implement OSPF because it handles unequal cost load balancing most efficiently using variance.

D. It should include a task that establishes a baseline before and after the configuration has been changed.

SPF and EIGRP, and their default metrics are configured the same. Router D has equal cost paths to networks where both paths are not r eally equal cost. For example, network 172.16.54.0 shows equal cost through both router B and router C, though in reality the cost is greater using router C. Other routers, though not shown, are connected to the 172.16.54.0 and 172.16.55.0 networks, and the same issues exist to those routers and the networks connected to them. What can be done so that data will be routed along the most optimal path in the network? （）

A. Redistribute connected interfaces on router B and router C

B. Set the maximum nu mber of equal cost paths to1 in all routers

C. When redistributing EIGRP into OSPF, set the external metric type to type E1

D. Adjust the default metrics in router B and router C so that the values are different in each router

E. None of these solut ions will fix the problem. Migrate to a single dynamic routing protocol
