What specification should we refer?
Only I can find is RFC2461 (Neighbor Discovery for IP Version 6 (IPv6)),
but I don't think the description about link-local address applies to host.
| 8. REDIRECT FUNCTION
| This section describes the functions related to the sending and
| processing of Redirect messages.
| Redirect messages are sent by routers to redirect a host to a better
| first-hop router for a specific destination or to inform hosts that a
| destination is in fact a neighbor (i.e., on-link). The latter is
| accomplished by having the ICMP Target Address be equal to the ICMP
| Destination Address.
| A router MUST be able to determine the link-local address for each of
| its neighboring routers in order to ensure that the target address in
| a Redirect message identifies the neighbor router by its link-local
| address. For static routing this requirement implies that the next-
| hop router's address should be specified using the link-local address
| of the router. For dynamic routing this requirement implies that all
| IPv6 routing protocols must somehow exchange the link-local addresses
| of neighboring routers.
