Configuring Static and Default Routes
Note The Tracked option is not supported for IPv6.
Step10 (Optional) Click Monitoring Options.
The Route Monitoring Options dialog box appears. From here, you change the following tracking object
monitoring properties:
•Frequency, which allows you to modify how often, in seconds, the ASA should test for the presence
of the tracking target. Valid values range from 1 to 604800 seconds. The default value is 60 seconds.
•Threshold, which 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, which 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 range from 0 to
604800000 milliseconds. The default value is 5000 milliseconds.
•Data Size, which 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 This setting specifies the size of the payload only; it does not specify the size of the entire
packet.
•ToS, which 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, which allows you to choose the number of echo requests to send for each test.
Valid values range from 1 to 100. The default value is 1.
Step11 Click OK.
Step12 Click Apply to save the configuration.
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.
Configuring Static Route Tracking
To configure tracking for a static route, perform the following steps:
Note Static route tracking is available for IPv4 routes only.
Step1 Choose a target of interest. Make sure that the target responds to echo requests.
Step2 Open the Static Routes pane by choosing Configuration> Device Setup > Routing > Static Routes.
Step3 Click Add to configure a static route that is to be used based on the availability of your selected target
of interest. You must enter the Interface, IP Address, Mask, Gateway, and Metric settings for this route.
Step4 Click the Track ed radio button in the Options area for this route.
Step5 Configure the tracking properties. You must enter a unique Track ID, a unique SLA ID, and the IP
address of your target of interest.
