Multi-Datacenter (Primary/Primary) Enterprise SD-WAN

[keithli_FTNT]

The following snippet summarizes the SD-WAN Multi-Datacenter (Primary/Primary) architecture and deployment guide for Enterprises. To view the complete guide, go to Multi-Datacenter (Primary/Primary) Enterprise SD-WAN.

Multiple datacenters (primary/primary gateways)

In this design, branch SD-WAN devices now have two (or more) gateways at separate geo-redundant locations from which to steer traffic. Both hub devices are primary instead of active/passive. This design is common where hub devices provide remote access to different resources.

•     Example 1: HUB1 in HQ, HUB2 in Datacenter
•     Example 2: HUB1 in Datacenter, HUB2 in AWS
•     Example 3: HUB1 in AWS, HUB2 in Azure

Deployment procedures

Following is a summary of the steps required to configure SD-WAN using FortiManager:

1. Configure the overlay using the SD-WAN overlay template. See Creating an overlay template.
2. Assign metadata values to branch devices. See Assigning meta data values to branch devices.
3. Configure SD-WAN rules. See Configuring SD-WAN rules.
4. Create normalized interfaces. See Creating normalized interfaces.
5. Create policy packages and firewall policies for hub and branch devices. See Creating policy packages and firewall policies.
6. Install policy packages to devices. See Installing policy packages.
7. Verify the SD-WAN configuration. See Verifying the SD-WAN configuration.
