Follow-up Comment #4, patch #7409 (project lwip):
As of RFC4443 4.2 An Echo Reply SHOULD be sent in response to an Echo Request
message sent to an IPv6 multicast or anycast address.
icmp6_input function of icmp6.c should rather not check
if (ip6_addr_ismulticast(ip6_current_dest_addr()))
to drop packets.
Lwip should join linklocal multicast group,
nd6_tmr function of nd6.c may have
ip6_addr_set_allnodes_linklocal(&multicast_address);
mld6_joingroup(netif_ip6_addr(netif, i), &multicast_address);
just like joining solicited node multicast group.
