Deployment objectives
This deployment guide is the supporting document to the Multiple datacenters (primary/secondary gateways) section of the SD-WAN Architecture for Enterprise guide. The use case covered in this document will support primary/secondary behavior of hubs in the SD-WAN region.
Deployment assumptions
- Greenfield deployment of new Fortinet Secure SD-WAN devices.
- Dual hub FortiGates will provide secure access to remote branch locations that require connectivity to local application and services.
- Primary hub (HUB1) will be the preferred hub location for all branch locations in the region.
- Secondary hub (HUB2) will be the backup hub location for all branch locations in the region.
- Traffic will go through primary location as long as the minimum SLA are being met. Traffic is to fail over when those SLA thresholds are no longer being met.
- Both hubs will advertise the same datacenter network space.
- Both hubs have two, redundant WAN connections.
- Each Branch location has two, redundant WAN connections
- WAN connections are public links that can reach all other devices in the region.
- All WAN interfaces have already been configured and have default gateways configured across both links.
