This changes behaviour of ping6 ff02::1%pppoe0 for me, previously I saw a response to each icmp message in the sequence, now I just see the first response. I am not using "set skip" on that machine.
$ ping6 ff02::1%pppoe0 PING6(56=40+8+8 bytes) fe80::225:90ff:fec0:77b4%pppoe0 --> ff02::1%pppoe0 16 bytes from fe80:15::225:90ff:fec0:77b4, icmp_seq=0 hlim=64 time=0.271 ms ^C --- ff02::1%pppoe0 ping6 statistics --- 6 packets transmitted, 1 packets received, 83.3% packet loss round-trip min/avg/max/std-dev = 0.271/0.271/0.271/0.000 ms
