IP address and subnet ranges for CPE devices

You can create ranges of IP addresses and subnets to centrally assign IPv4 addresses when creating or editing network interfaces of CPE devices. You can also use IP address ranges to centrally assign IPv4 addresses to router IDs of CPE devices when specifying basic BGP settings.

Managing IP address ranges

To display the table of IP address ranges, go to the SD-WAN → IPAM section. The IP Pool tab is selected by default. Information about IP address ranges is displayed in the following columns of the table:

• Name is the name of the IP address range.
• CIDR is the IPv4 prefix of the subnet in which the IP address range is located.
• IP range specifies the starting and ending values of the IP address range.
• Usage is the number of IP addresses in the range that have been assigned to network interfaces or router IDs of CPE devices.

The actions you can perform with the table are described in the Managing solution component tables instructions.

Creating a range of IP addresses

To create an IP address range:

1. In the menu, go to the SD-WAN → IPAM section.

   By default, the IP Pool tab is selected, displaying a table of IP address ranges.

2. In the upper part of the page, click + IP Pool.
3. This opens a window; in that window, in the Name field, enter the name of the IP address range. Maximum length: 32 characters.
4. In the CIDR field, enter the IPv4 prefix of the subnet in which the IP address range is located.
5. Specify a range of IP addresses. To do so, under IP range, click + Add and enter the starting and ending values of the IP address range.

   The IP address range is specified and displayed in the IP range section. You can specify multiple IP address ranges or delete an IP address range. To delete an IP address range, click the delete icon next to it.

6. Click Create.

The IP address range is created and displayed in the table.

Editing an IP address range

To change an IP address range:

1. In the menu, go to the SD-WAN → IPAM section.

   By default, the IP Pool tab is selected, displaying a table of IP address ranges.

2. Click the IP address range that you want to edit.
3. This opens a window; in that window, if necessary, edit the name and IPv4 prefix of the subnet containing the IP address range, and specify or delete the IP address ranges.

4. If you want to view information about IP addresses that have been assigned from the IP address range, select the Leases tab.

   A table of IP addresses assigned from the IP address range is displayed. Information about IP addresses is displayed in the following columns of the table:

   • IP is the IP address that has been assigned from the IP address range.
   • CPE is the CPE device to which the IP address is assigned.
   • Type indicates whether the IP address is assigned to a network interface or router ID of a CPE device.
   • Name is the name of the network interface to which the IP address is assigned. If an IP address has been assigned to the router ID of the CPE device, no value is displayed in this column.
   • Tenant is the tenant to which the CPE device has been added.

The actions you can perform with the lists and table are described in the Managing solution component tables instructions.

Deleting IP address ranges

You cannot delete an IP address range if it is being used by at least one CPE template or CPE device. You need to look up the usage of the IP address range and make sure that it is not being used.
