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

redistribution between EI GRP and OSPF. While verifying that the redistribution is functioning properly, you discover that while router C has all of the EIGRP routes in its routing table, router A does not have any routes from the EIGRP domain. What on router C may be the cause o f the problem?（）

A. The no auto - summary command needs to be added under router eigrp 1

B. The subnets keyword was not included in the redistribute command under router ospf 1

C. The metric specified for the redistributed EIGRP routes is too large; m aking the EIGRP routes unreachable by router A

D. The default - information originate command needs to be added under router ospf 1

E. The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distanc e than OSPF
