Mask a.b.c.d
The netmask specified with the IP address as explained above.
Include this route in RIP advertisements
When enabled, the router includes this static route to be included in RIP advertisements.
Make PPP x interface use the alternative idle timeout when this route becomes
available
When enabled, this check box, in conjunction with the PPP interface instance number in the text box,
cause the router to use the alternative inactivity timeout specified for that interface when this route
comes back into service. This feature is useful when it is preferable to close down a backup route
quickly when a primary route comes back into service.
Wait for s seconds after power up before allowing this route to activate the
interface
The delay that the router should wait after power-up before packets matching this route will initiate a
connection of the interface configured in the route. W-WAN routers that have ISDN backup typically
use this setting to prevent unnecessary ISDN connections from being made while a W-WAN connection
is first being established.
If the interface is configured for “dial on demand”
Mark this route as “Out Of Service” if the interface fails to connect after n
consecutive attempts
Normally, if an interface is requested to connect by a route and fails to connect, the route metric is set
to 16 for the period of time specified by the Mark a static route as Out Of Service for s seconds
parameter on the Configuration > Network > IP Routing/Forwarding > IP Routing page. If the
value in this text box is non-zero, the route metric will not be set to 16 until the number of connection
attempts specified by this parameter have been made.
If the interface fails to connect, try again in s seconds
If an interface is requested to connect by this route (due to IP traffic being present) and it fails to
connect, the route will be marked as out of service but the router will continue to attempt to connect
at the interval specified by the value in this text box. If the interface does connect, the router will clear
the out of service status for the route.
Deactivate the interface after it successfully connects
When enabled, the router deactivates an interface once a successful activation attempt has been
made. The router uses this setting with the above retry parameter. If the above retry parameter is
not set, this setting is disabled.
Do not allow this interface to be activated by this route for s seconds after the
last activation attempt
The delay to wait before re-initiating a connection after it has dropped while still required.
