Maybe we could say - Further, this document specifies a new TLV called LINKLOCAL-IPV6-ADDRESS to describe an IPv6 adjacency for an interface that does not have a global IPv6 address assigned. Erik suggested using ONLINK instead of LINKLOCAL for the TLV name. I am not sure, to me using LINKLOCAL to match with RFC 8664 seems to be okay. Any thoughts on that? Thanks!
