maximum-paths path-number
Example:
switch(config-router)# maximum-paths 4
This example shows how to create an OSPFv2 instance:
switch# configure terminal
switch(config)# router ospf 201
switch(config-router)# copy running-config startup-config

Note
OSPF is not enabled on an interface until you configure a valid IP address for that interface.
