Backup IP Gateway Settings
The purpose of Backup is to provide a recover y mechanism in the event that the primar y
connection fails. A failure can be either line loss, for example by central site switch failure
or physical cable breakage, or loss of end-to-end connectivity. Detection of one of these
failures causes the Gateway to switch from using the primar y DSL WAN connection to an
alternate gateway on the Ethernet LAN. In the event of a loss of primar y connectivity you
have the option of switching back to the primar y circuit automatically once it has recovered
its connection.
A typical application would be to have a LAN connection from your Gateway to another
Gateway that has, for example, another DSL modem or Gateway connection to the Internet,
and designating the second gateway as the backup gateway. Should the primar y WAN
connection fail, traffic would be automatically redirected through your alternate gateway
device to maintain Internet connectivity.
set backup option [ disabled | manual | automatic ]
Specifies whether backup to an IP gateway is
disabled
or enabled as
manual
or
auto-
matic
. Default is
disabled
.
set backup failure-timeout [ 1 - 10 ]
Specifies the number of minutes you want the system to wait before the backup por t
becomes enabled in the event of primar y line failure, when
backup option
is set to
auto-
matic
. Sets the Default is
1
.
set backup ping-host [ 1 | 2 ] [ name | address ]
Specifies whether the Gateway will ping an IP address or resolvable DNS name, when
backup option
is set to
automatic
. These are optional items that are par ticularly useful
for testing if the remote end of a VPN connection has gone down.
The Gateway will ping both addresses simultaneously at five-second inter vals, recording
the ping responses from each host. The Gateway will proceed into backup mode only if nei-
ther of the configured remote hosts responds.
