Chapter 25 Configuring Static and Default Routes
Configuring Static and Default Routes
Step 6 (Optional) To configure the monitoring properties, click Monitoring Options in the Add Static Route
dialog box.
Step 7 Click OK to save your changes.
The monitoring process begins as soon as you save the tracked route.
Step 8 Create a secondary route by repeating Steps 1 through 7.
The secondary route is a static route to the same destination as the tracked route, but through a different
interface or gateway. You must assign this route a higher administrative distance (metric) than your
tracked route.
Step 9 Click OK to save your changes.
Deleting Static Routes
To delete a static route, perform the following steps:
Step 1 Choose Configuration > Device Setup > Routing > Static Routes.
Step 2 On the Static Routes pane, choose which route to delete.
By default, the Both radio button is checked, and both IPv4 and IPv6 addresses appear in the pane.
• To limit your viewed choices to routes configured with IPv4 addresses, click the IPv4 radio button.
• To limit your viewed choices to routes configured with IPv6 addresses, click the IPv6 radio button.
Step 3 Click Delete.
The deleted route is removed from list of routes on in the main Static Routes pane.
Step 4 Click Apply to save the changes to your configuration.
Configuring a Default Static Route
A default route identifies the gateway IP address to which the ASA sends all IP packets for which it does
not have a learned or static route. A default static route is simply a static route with 0.0.0.0/0 as the
destination IP address. Routes that identify a specific destination take precedence over the default route.
Note In Versions 7.0(1) and later, if you have two default routes configured on different interfaces that have
different metrics, the connection to the ASA that is made from the higher metric interface fails, but
connections to the ASA from the lower metric interface succeed as expected.
You can define up to three equal cost default route entries per device. Defining more than one equal cost
default route entry causes the traffic sent to the default route to be distributed among the specified
gateways. When defining more than one default route, you must specify the same interface for each
entry.
If you attempt to define more than three equal cost default routes or a default route with a different
interface than a previously defined default route, you receive the following message:
“ERROR: Cannot add route entry, possible conflict with existing routes.”
