Presumably you're doing this from a Linux host.  You might try these
flags to see what you get:

       -T, --tcp
            Use TCP SYN for probes

       -e, --extensions
              Show  ICMP  extensions  (rfc4884).  The  general  form is CLASS/TYPE: followed by a hexadecimal dump.  The MPLS (rfc4950) is shown
              parsed, in a form: MPLS:L=label,E=exp_use,S=stack_bottom,T=TTL (more objects separated by / ).

and a good general reference for the netop:
