Citrix SD-WAN

Inline mode

This article provides the detail on configuring a branch with Inline Deployment mode. In this mode, the SD-WAN appliance appears to be an Ethernet bridge. Most of the SD-WAN appliance models include a fail-to-wire (Ethernet bypass) feature for inline mode. If power fails, a relay closes and the input and output ports become electrically connected, allowing the Ethernet signal to pass through from one port to another. In the fail-to-wire mode, the SD-WAN appliance looks like a cross-over cable connecting the two ports.

In the following diagram interfaces 1/1 and 1/2 are hardware bypass pairs and will fail-to-wire connecting the Core to the edge MPLS Router. Interfaces 1/3 and 1/4 are also hardware bypass pairs and will fail-to-wire connecting the Core to the edge Firewall. For more information on SD-WAN Orchestrator service-based Inline mode deployment, see Interfaces.
