When monitoring the OSPF operations in the network, you notice that the OSPF process is not
load balancing traffic across multiple OSPF links. Which configuration adjustment could be made
to enable the OSPF process to load balance traffic across multiple OSPF links?
A.
Enable BFD on the OSPF interfaces and on the OSPF routing process.
B.
Enable NSR on the OSPF routing process.
C.
Enable NSF on the OSPF routing process.
D.
Adjust the OSPF cost on the OSPF interfaces.
E.
Adjust the OSPF variance parameter.
F.
Use the wide-style OSPF metric instead of the narrow-style OSPF metric.
Explanation:
Sometimes the router must select a route from among many learned via the same routing process with the same administrative distance. In this case, the router chooses the path with the lowest cost (or metric) to the destination. Each routing process calculates its cost differently and the costs may need to be manipulated in order to achieve load-balancing.
If the router receives and installs multiple paths with the same administrative distance and cost to a destination, load-balancing can occur. The number of paths used is limited by the number of entries the routing protocol puts in the routing table. Four entries is the default in IOS for most IP routing protocols.
