RADVD Status Check Enable to enable RADVD, or check Disable to
disable RADVD.
Advertise Mode Select one of the following modes:
• Unsolicited Multicast: Select this mode to
send Router Advertisements (RAs) to all
interfaces belonging to the multicast group.
• Unicast Only: Select this mode to restrict
advertisements to well-known IPv6 addresses
only (RAs are sent to the interface belonging to
the known address only).
Advertise Interval If you choose Unsolicited Multicast as the advertise
mode, enter the advertise interval (4 to 1800). The
default is 30. The advertise interval is a random value
between the Minimum Router Advertisement Interval
(MinRtrAdvInterval) and Maximum Router
Advertisement Interval (MaxRtrAdvInterval).
MinRtrAdvInterval = 0.33 * MaxRtrAdvInterval
RA Flags Check Managed to use the administered/stateful
protocol for address auto configuration.
Check Other to use the administered/stateful protocol
of other, non-address information auto configuration.
Router Preference Choose low, medium, or high from the drop-down
menu. The default is medium.
The router preference provides a preference metric for
default routers. The low, medium and high values are
signaled in unused bits in RA messages. This
extension is backward compatible, both for routers
(setting the router preference value) and hosts
(interpreting the router preference value). These values
are ignored by hosts that do not implement router
preference. This feature is useful if there are other
RADVD-enabled devices on the LAN.
