Hot-Standby -
Such method is suitable when there is only one ISP account.
When this method is selected,
 During normal operation the secondary router will be
idling. When the primary router fails to operate
normally, the secondary router(s) will take over.
 WAN settings of the primary and secondary routers are
identical.
Note: When Hot-Standby is used, the wireless LAN
function on secondary router will be “disabled”
directlly. Clients can not connect to the secondary
router any more.
Active-Standby -
This method is suitable when there are multiple
simultaneously active ISP connections. When this method is
selected,
 All WANs on the secondary routers can be up at the
same time. LANs that are not configured under high
availability can be routed to secondary routers.
 WAN settings of primary and secondary routers are
independently configured.
 Config Sync may be enabled to synchronize most
configuration settings between the primary and
secondary routers.
 All routers must be set to the same redundancy
method.
Group ID Type a value (1~255).
In LAN environment, multiple routers can be devided into
several groups. Each router must be specified with one group
ID. Different routers with the same ID value will be
categoried into the same group.
Only one of the routers in the same group will be selected as
the primary router.
Priority ID Type a value (1~30).
Different routers must be configured with different IDs.
All routers within a group must be assigned a priority ID.
Within a group, the router with the largest priority ID (i.e.,
the highest priority) will be the primary router. When
multiple routers in a group are assigned the same priority ID,
routers with lower LAN IP addresses (configured on the LAN
>> General Setup page) have higher priority.
Authentication Key Enter an authentication key up to 31 characters long. This is
used to encrypt the DARP (DrayTek Address Redundancy
Protocol) traffic to guard against malicious attacks.
Protocol Select the IP protocol to be used for DARP.
Management Interface Select the interface to be used for DARP negotiation
between routers. Only interfaces which are enabled in
LAN>>General Setup are available for selection.
However, LAN1 is always enabled.
Update DDNS Enable – Check the box to update the DDNS server for the
secondary device when the primary router fails.
If the primary device fails, and the secondary device must
take over the job of data transmitting and receiving. Then
