You configured multiple external interfaces on your Firebox and a BOVPN virtual interface to a remote site. How can you configure the local Firebox to failover the BOVPN virtual interface?

The correct choice involves adding the backup external interface to the Gateway Endpoints list in the BOVPN Virtual Interface settings. This configuration is essential for establishing a reliable failover mechanism for the VPN connection.

When configuring a BOVPN (Branch Office VPN) to use multiple external interfaces, it's crucial to specify the gateways that allow the Firebox to detect and respond to network changes. By including the backup external interface in the Gateway Endpoints list, the Firebox is informed of alternate paths it can take if the primary link becomes unavailable. This setup ensures continuous connectivity to the remote site under normal operational conditions as well as during disruptions.

Including the backup interface in the configuration allows the Firebox to automatically and seamlessly switch from the primary to the secondary interface if needed, thus maintaining the availability of the BOVPN tunnel. This failover feature is vital for businesses that rely on consistent network connectivity for critical applications and services.

The other options, while they might seem relevant, do not provide the necessary configuration to facilitate the failover process directly. For instance, simply enabling an SD-WAN action in policies or adding routing configurations might not adequately address the need for a backup external interface to be prepared for a sudden switch. The direct configuration of Gateway Endpoints is
