Chapter 19 Configuring Static and Default Routes
Tunneled—This option specifies the route as the default tunnel gateway for VPN traffic. This option
•
is used for the default route only. You can configure only one tunneled route per device. The
tunneled option is not supported under transparent mode.
Tracked—This option specifies that the route is tracked. The tracking object ID and the address of
•
the tracking target also appear. The tracked option is supported in single, routed mode only.

Step 10
The Route Monitoring Options dialog box appears. From here you change the following tracking object
monitoring properties:
Frequency—Allows you to modify how often, in seconds, the adaptive security appliance should test
•
for the presence of the tracking target. Valid values are from 1 to 604800 seconds. The default value
is 60 seconds.
Threshold—Allows you to enter the amount of time, in milliseconds, that indicates an
•
over-threshold event. This value cannot be more than the timeout value.
Timeout—Allows you to modify the amount of time, in milliseconds, that the route monitoring
•
operation should wait for a response from the request packets. Valid values are from 0 to 604800000
milliseconds. The default value is 5000 milliseconds.
• Data Size—Allows you to modify the size of data payload to use in the echo request packets. The
default value is 28. Valid values range from 0 to 16384.
Note
ToS—Allows you to choose a value for the type of service byte in the IP header of the echo request.
•
Valid values are from 0 to 255. The default value is 0.
Number of Packets—Allows you to choose the number of echo requests to send for each test. Valid
•
values are from 1 to 100. The default value is 1.
Click OK.
Step 11
Click Apply to save the configuration.
Step 12
The added or edited route information appears in the Static Routes pane. The monitoring process begins
as soon as you save the newly configured route.
OL-20339-01
Track ID—Enter a unique identifier for the route tracking process.
Track IP Address/DNS Name—Enter the IP address or hostname of the target being tracked.
Typically, this would be the IP address of the next hop gateway for the route, but it could be any
network object available off of that interface.
SLA ID—Enter a unique identifier for the SLA monitoring process.
The Tracked option is not supported for IPv6.
This setting specifies the size of the payload only; it does not specify the size of the entire
packet.
