SD-WAN Deployment Modes by Vendors



    • HPE/Silver Peak Deployment Modes


    ▶ Router Mode

    - Can be in-line or out-of-path and uses multiple ports. Best for complex networks.

    ○ Do you want your traffic to be in-path or out-of-path? This mode supports both deployments. In-path deployment offers much simpler configuration.

    ○ Does your router support VRRP, WCCP, or PBR? If so, you may want to consider out-of-path Router mode deployment. You can set up more complex configurations, which offer load balancing between appliances and high availability.

    ○ If your LAN destination is behind a router or L3 switch, you need to add a LAN-side route (a LAN next-hop).


    ▶ Bridge Mode

    - Can only be in-line and uses 2 or 4 ports. Easiest setup for simple networks.

    ○ Do you have a physical appliance or a virtual appliance?

    ○ A virtual appliance has no fail-to-wire, so you need a redundant network path to maintain connectivity if the appliance fails.

    ○ If your LAN destination is behind a router or L3 switch, you need to add a LAN-side route (a LAN next-hop).

    ○ If the appliance is on a VLAN trunk, then you need to configure VLANs on the Silver Peak so that the appliance can tag traffic with the appropriate VLAN tag.


    ▶ Server Mode

    - Can only be out-of-path and uses 1 port (mgmt0). Best for backup configurations.

    For more detail, please refer to the Silver Peak SD-WAN Deployment Guide.
