One or more [IPv6Prefix] sections contain the IPv6 prefixes that
are announced via Router Advertisements. See RFC 4861
AddressAutoconfiguration=, OnLink=
Takes a boolean to specify whether IPv6 addresses can be
autoconfigured with this prefix and whether the prefix can be
used for onlink determination. Both settings default to
"true" in order to ease configuration.
Prefix=
The IPv6 prefix that is to be distributed to hosts. Similarly
to configuring static IPv6 addresses, the setting is
configured as an IPv6 prefix and its prefix length, separated
by a "/" character. Use multiple [IPv6Prefix] sections to
configure multiple IPv6 prefixes since prefix lifetimes,
address autoconfiguration and onlink status may differ from
one prefix to another.
PreferredLifetimeSec=, ValidLifetimeSec=
Preferred and valid lifetimes for the prefix measured in
seconds. PreferredLifetimeSec= defaults to 604800 seconds
(one week) and ValidLifetimeSec= defaults to 2592000 seconds
(30 days).
Assign=
Takes a boolean. When true, adds an address from the prefix.
Default to false.
RouteMetric=
The metric of the prefix route. Takes an unsigned integer in
the range 0...4294967295. When unset or set to 0, the
kernel's default value is used. This setting is ignored when
Assign= is false.
