It's not. There is the well-known ff02::2 "all routers on local segment"
multicast address, but ff08::2 (::2 in the well-known organization-local
scope ff08::/16 range) ain't officially assigned:
http://www.iana.org/assignments/ipv6-multicast-addresses/ipv6-multicast-addresses.xhtml#ipv6-multicast-addresses-4

This looks like abuse of the well-known range, using unassigned ::2

Best regards,
Daniel
