toobigsniff6 [-c] interface target mtu
Sniff for packte from target and send an ICMPv6 too big error message based on that packet with the MTU specified. If you supply a '*' as-address, any global traffic sniffed will be used. If you supply the option -c the tool will not quit upon first packet match, but continue running and send packets until aborted.
