How does the EIGRP metric differ from the OSPF metric?
A . The EIGRP metric is calculated based on bandwidth only. The OSPF metric is calculated on delay only.
B . The EIGRP metric is calculated based on delay only. The OSPF metric is calculated on bandwidth and delay.
C . The EIGRP metric Is calculated based on bandwidth and delay. The OSPF metric is calculated on bandwidth only.
D . The EIGRP metric Is calculated based on hop count and bandwidth. The OSPF metric is calculated on bandwidth and delay.

Answer: C

Explanation:

By default, EIGRP metric is calculated:

metric = bandwidth + delay

While OSPF is calculated by:

OSPF metric = Reference bandwidth / Interface bandwidth in bps

(Or Cisco uses 100Mbps (108) bandwidth as reference bandwidth.

With this bandwidth, our equation would be:

Cost = 108/interface bandwidth in bps)
