Function

The debugging ospf spf command enables debugging of the shortest path tree calculation and next hops of all OSPF processes.

The undo debugging ospf spf command disables debugging of the shortest path tree calculation and next hops of all OSPF processes.

By default, the debugging of the shortest path tree calculation and next hops of all OSPF processes is disabled.
