   Company XYZ has two routing domains in their network EIGRP and OSPF. The company wants to provide full reachability between the two domains by implementing redistribution on a router running both protocols. They need to design the redistribution in a way that the OSPF routers will see link costs added to external routes. How must the redistribution strategy be designed for this network?

   • ARedistribute using metric type 2 into OSPF
   • BRedistribute using metric type 1 into OSPF
   • CRedistribute using metric type 2 into EIGRP
   • DRedistribute using metric type 1 into EIGRP
