Refer to the exhibit. You are migrating a network from IGRP to OSPF. What must you do to ensure that connectivity and reachability of all networks is maintained between routing protocols when OSPF has the longer subnet mask?
A.
Use the default metric of 1.
B.
Add a static route in the gateway router for 128.103.35.0/24 pointing to null0.
C.
Add multiple static routes in the gateway router pointing to the OSPF network.
D.
This scenario should not present any reachability problems if the autonomous systems are the same.
