Managing OSPF interfaces

The table of OSPF interfaces is displayed in the CPE template and on the CPE device:

• To display the table of OSPF interfaces in a CPE template, go to the SD-WAN → CPE templates menu section, click the CPE template, and select the OSPF → OSPF interface tab.
• To display the table of OSPF interfaces on a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, and select the OSPF → OSPF interface tab.

Information about OSPF interfaces is displayed in the following columns of the table:

• Interface is the network interface used as an OSPF interface.
• OSPF area is the ID of the OSPF area to which the OSPF interface belongs.
• Authentication is the authentication method.
• Network type is the type of network to which the OSPF interface is connected.
• Management contains the actions that can be performed with the OSPF interface.

Creating an OSPF interface

You can create an OSPF interface in a CPE template or on a CPE device. An OSPF interface created in the CPE template is automatically created on all CPE devices that use this CPE template.

To create an OSPF interface:

1. Create an OSPF interface in one of the following ways:
   • If you want to create an OSPF interface in a CPE template, go to the SD-WAN → CPE templates menu section, click the CPE template, and select the OSPF → OSPF interface tab.
   • If you want to create an OSPF interface on a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, select the OSPF → OSPF interface tab, and select the Override check box.

   A table of OSPF interfaces is displayed.

2. Click + OSPF interface.
3. This opens a window, in that window, in the Interface drop-down list, select the created network interface which you want to use as an OSPF interface.
4. In the OSPF area field, enter the ID of the OSPF area to which the OSPF interface belongs, as an IPv4 address or an integer number.
5. If you want to specify OSPF authentication:
   1. In the Authentication drop-down list, select an authentication method:
      • Message digest to use the MD5 algorithm.
      • Simple password to use an unencrypted password. This authentication method is less secure than MD5 algorithm, however, it can provide authentication when used in a trusted network environment. If you select this option, enter the authentication password in the Password field.
   2. If in the Authentication drop-down list, you selected Message digest, follow these steps:
      1. In the Key ID field, enter the MD5 hash. Range of values: 1 to 255.
      2. In the Key field, enter the MD5 key.
6. In the Cost field, enter the metric of the OSPF interface. Range of values: 1 to 65,535.
7. In the Network type drop-down list, select the type of network to which the OSPF interface is connected:
   • Broadcast
   • Non-broadcast
   • Point-to-multipoint
   • Point-to-point
8. In the Priority field, enter the priority of the OSPF interface. The greater the value, the higher the priority of the OSPF interface.

   The highest-priority OSPF interface becomes the designated router of the network segment. The OSPF interface with the second highest priority becomes the backup designated router.

9. If you want to switch the OSPF interface to passive mode, select the Passive interface check box. In passive mode, OSPF interfaces do not exchange traffic packets.
10. If you want to use the BFD protocol to detect loss of connectivity, select the BFD check box. This check box is cleared by default.
11. If you want to configure OSPF timers:
    1. Select the OSPF timers check box. This check box is cleared by default.
    2. In the Hello (sec.) field, enter the time interval in seconds that the OSPF interface uses to send control packets to OSPF neighbors. Range of values: 1 to 65,535.
    3. In the Dead (sec.) field, enter the time interval in seconds that the OSPF interface uses to receive control packets from OSPF neighbors. If no control packets are received from an OSPF neighbor within the specified time, the OSPF interface considers this OSPF peer unavailable. Range of values: 1 to 65,535.
12. In the Retransmit interval (sec.) field, enter the time after which the OSPF resends lost traffic packets. Range of values: 1 to 65,535.
13. Click Create.

    The OSPF interface is created and displayed in the table.

14. In the upper part of the settings area, click Save to save the settings of the CPE template or CPE device.

Editing an OSPF interface

You can edit an OSPF interface in a CPE template or on a CPE device. An OSPF interface edited in the CPE template is automatically modified on all CPE devices that use this CPE template.

To edit an OSPF interface:

1. Edit an OSPF interface in one of the following ways:
   • If you want to edit an OSPF interface in a CPE template, go to the SD-WAN → CPE templates menu section, click the CPE template, and select the OSPF → OSPF interface tab.
   • If you want to edit an OSPF interface on a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, select the OSPF → OSPF interface tab, and select the Override check box.

   A table of OSPF interfaces is displayed.

2. Click Edit next to the OSPF interface that you want to edit.
3. This opens a window; in that window, if necessary, edit the OSPF interface settings. For a description of the settings, see the instructions for creating an OSPF interface.
4. Click Save.

   The OSPF interface is modified and updated in the table.

5. In the upper part of the settings area, click Save to save the settings of the CPE template or CPE device.

Deleting an OSPF interface

You can delete an OSPF interface in a CPE template or on a CPE device. An OSPF inerface deleted in the CPE template is automatically deleted on all CPE devices that use this CPE template.

Deleted interfaces cannot be restored.

To delete an OSPF interface:

1. Delete an OSPF interface in one of the following ways:
   • If you want to delete an OSPF interface in a CPE template, go to the SD-WAN → CPE templates menu section, click the CPE template, and select the OSPF → OSPF interface tab.
   • If you want to delete an OSPF interface on a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, select the OSPF → OSPF interface tab, and select the Override check box.

   A table of OSPF interfaces is displayed.

2. Click Delete next to the OSPF interface that you want to delete.
3. In the confirmation window, click Delete.

   The OSPF interface is deleted and is no longer displayed in the table.

4. In the upper part of the settings area, click Save to save the settings of the CPE template or CPE device.
