Iron metal has undergone oxidation, as its oxidation state is changing from 0 to +2 and +3. Iron metal is getting converted into Iron ions.

Hydrogen has undergone reduction, as its oxidation state is changing from 2+ to 0.Hydrogen ions are getting converted into hydrogen.

FeFe is a reducing agent

Those chemical agents which get oxidized itself and reduce others is called reducing agents.
