When the host sends an IPv6 packet, if the prefix
of the destination address matches the set prefix,
it is considered that the destination is on-link and
is directly reachable. If this option is set, it
indicates that the prefix is not used for on-link
judgment.

By default, the advertised prefix is the one set with ipv6 address on
the interface. The default parameters of the prefix configured in the
RA are as follows:
