The flow label in an IPv6 packet does not represent -1. The TC is called IPv6FlowLabelOrAny and the -1 stands for "any"; a special value which is used to indicate that any flow label value is matched in say a filter expression. If you want to represent a flow label alone, use the IPv6FlowLabel TC defined in the same RFC. /js -- Juergen Schoenwaelder International University Bremen <http://www.eecs.iu-bremen.de/> P.O.
