What is the default maximum number of equal-cost paths that can be placed into the routing table of a Cisco OSPF router?
A. 2
B. 4
C. 16
D. unlimited
Answer: B
Explanation:
4 is the default number of routes that OSPF will include in routing table if more than 4 equal cost routes exist for the same subnet. However, OSPF can include up to 16 equal cost routes in the routing table and perform load balancing amongst them. In order to configure this feature, you need to use the OSPF subcommand maximum-paths, i.e. maximum-paths 16.

The default OSPF maximum number for equal-cost paths is dependent on the software version and platform. For NX OS the default is 8. For other versions it is 4. If you get this question on the exam it is unlikely they will have 4 and 8 both as an option. Pick either 4 or 8 depending on the options.
