Backup Ip Gateway Settings - Motorola 2200 Administrator's Handbook

Backup IP Gateway Settings

The purpose of Backup is to provide a recovery mechanism in the event that the primary connection fails.
Should the primary WAN connection fail, traffic would be automatically redirected through your alternate
gateway device to maintain Internet connectivity. See "Backup" on page 133 for more information.
set backup option [ disabled | manual | automatic ]
Specifies whether backup to an IP gateway is disabled or enabled as manual or automatic. Default is dis-
abled.
set backup failure-timeout [ 1 - 10 ]
Specifies the number of minutes you want the system to wait before the backup port becomes enabled in
the event of primary line failure, when backup option is set to automatic. 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 particularly useful for testing if the remote end of a VPN
connection has gone down.
The Gateway will ping both addresses simultaneously at five-second intervals, recording the ping responses
from each host. The Gateway will proceed into backup mode only if neither of the configured remote hosts
responds.
set backup ping-host [ 1 | 2 ] [ name hostname | ip-address ip_address ]
Specifies an IP address or resolvable DNS name for the Gateway to ping.
set backup auto-recovery [ off | on ]
Turns automatic recovery off or on. Default is off.
set backup recovery-timeout [ 1 - 10 ]
If auto-recovery is set to on, specifies the number of minutes for the system to wait before attempting to
switch back to the WAN connection. This allows you to be sure that the WAN connection is well re-estab-
lished before the gateway switches back to it from the backup mode. Default is 1.
set ip backup-gateway option [ on | off ]
Turns the backup gateway option on or off. Default is off.
set ip backup-gateway interface ip-address
Specifies the backup gateway interface ip address to which you want to direct the backup connection.
