SD-WAN spoke
A spoke can be defined as any device in a corporate region that initiates an IPsec connection to a central location (hub). Traditionally, spokes are corporate locations that require access to a resource hosted at the hub location. Spokes connect to the hub as the IPsec initiator and peer with the hub by using BGP for routing between the SD-WAN region.
Spokes are often called branch locations, but can be any remote location that needs to connect to a corporate resource behind the hub. Common examples of spoke locations include:
- Branch offices
- Retail locations
- Gas stations
- Other corporate locations
Spoke locations that need access to private resources behind the hub(s) may access it directly. When resources are located at another spoke location, they may connect directly through a dynamic ADVPN connection.
