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.
