Managing prefix lists

The table of prefix lists is displayed in the CPE template and on the device:

• To display the table of prefix lists in a CPE template, go to the SD-WAN → CPE templates menu section, click the template, and in the displayed settings area, select the Routing filters → Prefix lists tab.
• To display the table of prefix lists on a CPE device, go to the SD-WAN → CPE menu section, click the device, and in the displayed settings area, select the Routing filters → Prefix lists tab.

Information about prefix lists is displayed in the following columns of the table:

• Name is the name of the prefix list.
• Inherited specifies whether the prefix list is inherited from the CPE template:
  • Yes
  • No

  This column is displayed only on the CPE device.

• Sequence is the sequence number of the rule in the prefix list. The rule with the lowest sequence number is the first to be applied to the IPv4 prefix by the prefix list.
• Network is the IPv4 prefix to which the prefix list must apply the rule.
• Action is the action that the rule performs on an IPv4 prefix:
  • Permit allows the IPv4 prefix.
  • Deny denies the IPv4 prefix.
• Greater or equal is the start value of the range of subnet masks to which the prefix list must apply the rule.
• Less or equal is the end value of the range of subnet masks to which the prefix list must apply the rule.
• Management contains the actions that can be performed on the prefix list.
