Your network has a mixture of Fast Ethernet and Gigabit Ethernet links. What needs to be
done to ensure optimal data routing when using OSPF? Select the best response.
A.
Nothing. OSPF will determine the most optimal path for routing data by default.
B.
Adjust the hello and dead timers for more rapid detection of link failures.
C.
Increase the reference-bandwidthused to calculate the interface default metrics, on
all routers in your network.
D.
Set the priority values on every broadcast interface to ensure that the designated and
backup designated routers are the routers with the most processor and memory
resources.
Explanation:
The default formula to calculate the cost for the OSPF metric is (108/BW). Therefore when
using default reference bandwidth (100M) to calculate ospf, Gi and Fa interfaces could have
the same cost (1). This problem can be fixed by configuring reference bandwidth to 1000M.
