You can configure BFD for OSPF for Profiles.

By default, BFD is deactivated in OSPF. You can enable BFD for OSPF to subscribe to BFD session updates.

Enabling BFD for an OSPF neighbor does not create a BFD session. You must explicitly configure a BFD session. See Configure BFD for Profiles.

The following procedure describes how to enable BFD for an already configured OSPF session on an Edge Interface. To configure OSPF settings, see Activate OSPF for Profiles.

To configure the Interface settings, see Configure Interface Settings for Profiles.

Procedure

  1. In the SD-WAN service of the Enterprise portal, click Configure > Profiles.
  2. Select a profile you want to configure BFD for OSPF settings and click the View link in the Device column of the Profile. The Device page for the selected Profile appears.
  3. In the Device tab, scroll down to the Connectivity section and click Interfaces. The Edge models available in the selected Profile are displayed.
  4. In the Interfaces section, click an Edge model to view the interfaces available in the Edge and select an interface to edit the settings.
  5. In the Interface edit window, you can configure OSPF settings under IPv4/IPv6 Settings. Select the OSPF check box and choose the OSPF Area from the drop-down list.
  6. Expand Advanced Settings and in the Custom Settings tab, select the Enable BFD check box.
  7. Configure the other settings as required and click Save.

Results

When you enable BFD for an OSPF area in a profile, the setting is automatically applied to the corresponding Edges that are associated with the profile. If required, you can override the configuration for a specific Edge . See Configure BFD for OSPF for Edges for more information.

When an OSPF neighbor receives an update that BFD session is down, the corresponding OSPF session immediately goes down and the routes are flushed without waiting for the expiry of keepalive timer.
