OSPF Maximum Paths

OSPF Maximum Paths :

Open Shortest Path First (OSPF) does equal cost load balancing. It is used to perform dynamic routing by exchanging routing table information using LSAs within a single Autonomous System (AS) in a network. And if you have multiple routes with equal cost paths to the same destination, then OSPF will do load sharing. OSPF allows entry of up to 4 multiple paths of a single network with identical metrics by default, and can be increased to a maximum of 16 paths and a minimum of 1 path.  Default settings and range of Maximum-paths vary depending on router platform/model....
