In RFC 791 page 14 it says
The copied flag indicates that this option is copied into all fragments on fragmentation.
0 = not copied 1 = copied
If I understand correctly it is possible to specify a different route with the strict or loose source routing options. If that is done, is it required to set these options in every fragment?
Or is there any other example where an option must be in every fragment? Is it the same as options in RFC 791 which "Must be copied on fragmentation." ?
