NEW QUESTION: 1
Consider a network that mixes link bandwidths from 128 kb/s to 40 Gb/s. Which value should be set for the OSPF reference bandwidth?
A. Set a value of 128.
B. Set a value of 40000.
C. Set a value of 65535.
D. Set a value of 40000000.
E. Set a manual OSPF cost on each interface.
F. Use the default value.
Answer: E
Explanation:
Explanation/Reference:
Explanation:
Unlike the metric in RIP which is determined by hop count and EIGRP's crazy mathematical formulated metric, OSPF is a little more simple. The default formula to calculate the cost for the OSPF metric is (10
By default the metrics reference cost is 100Mbps, so any link that is 100Mbps will have a metric of a T1 interface will have a metric of 64 so in this case if a router is trying to get to a FastEthernet network on a router that is through a T1 the metric would be 65 (64 +1).
You do however have the ability to statically specify a metric on a per interface basis by using the ip ospf cost # where the cost is an integer between 1-65535.
So the big question is why would you want to statically configure a metric?
The biggest advantage of statically configuring an OSPF metric on an interface is to manipulate which route will be chosen dynamically via OSPF. In a nut shell it's like statically configuring a dynamic protocol to use a specific route. It should also be used when the interface bandwidths vary greatly (some very low bandwidth interfaces and some very high speed interfaces on the same router).
