Clustered Multi-Link VPNs

Secure SD-WAN in the Engine/VPN role provides fast, secure, and reliable VPN connections. The added benefits of the clustering and Multi-Link technologies provide load balancing and failover for both the VPN gateways and the network connections.

The system’s scalability allows you to control how many tunnels are created and used.

The VPN links can be in three different modes:

• Active — When there are multiple links in active mode, traffic is dynamically balanced across the different links based on a performance measurement or based on the relative bandwidths of the links.
• Aggregate — When there are multiple links in aggregate mode, each connection is balanced between all the aggregate links in round robin fashion.
• Standby — Standby links are only used if the active or aggregate links fail.
