I would guess that's an embedded scope (and must not appear on the wire).
sin6->sin6_addr.s6_addr16[1] = htons(zoneid & 0xffff);
where zoneid for a link-local address like ff02:: (or an interface-local
address) is the interface index.
But ff02::1:ff02:2 would be a solicited-node multicast address for
something with an anycast or unicast address of anything:XX02:0002.
Such addresses are used as the part of neighbour discovery called
duplicate address detection.
Did you configure an IPv6 address that ends on XX02:0002 ?
