Configuring an IPv4 prefix list

FortiADC supports IPv4 prefix lists over BGP routing. If you are configuring BGP routing using IPv4, you must configure prefix lists using the IPv4 protocol.

To configure an IPv4 prefix list:

1. Go to Network > Routing.
2. Click the Prefix List tab.
3. Click Create New to display the configuration editor.
4. Configure the following Prefix List settings:
   

   Setting	Guideline
   Name	Enter a unique name for the new access list. The name can be up to 35 alphanumeric characters long, including . (period) , : (colon), _ (underscore), and - (hyphen). No space is allowed.
   Description	Optionally, enter a brief description of the access list. The description can be up to 1023 alphanumeric characters long, with no restriction on use of special characters. Space between characters is allowed.

5. Click Save.
   Once the Prefix List configuration is saved, the Rule will be available to configure.
6. In the Rule section, click Create New to display the configuration editor.
7. Configure the following Prefix List Rule settings:
   

   Setting	Guideline
   Action	Select the action as Permit or Deny.
   IPv4 Prefix	Enter the IPv4 address/subnet mask in the format of 0.0.0.0./0.
   GE	Specify the GE (greater than and equal to) values. Set to 0 or a number larger than netmask.
