Terms in this definition
- Geographic
A Traffic Manager routing method that picks the endpoint according to where the user is located geographically.
- Azure Machine Learning component
Reusable building block for a pipeline, versioned and self-contained, much like a function: it declares a name, inputs and outputs, and bundles the command, code and environment it runs.
- Virtual hub
Inside a Virtual WAN, a VNet managed by Microsoft that contains the hub router plus the VPN, ExpressRoute and User VPN gateways. Typically there is one per region, but several hubs can share a region.
- BGP
Dynamic routing protocol used with both ExpressRoute and VPN connections. On ExpressRoute private peering it is the only way to exchange routes, including a 0.0.0.0/0 default route for forced tunnelling.
Related terms
- NVA in the hub
A partner appliance, whether SD-WAN, NGFW or both, placed straight into a Virtual WAN hub where it runs BGP with the hub router. Each hub can hold only one.
- SD-WAN NVA
NVA deployed inside a Virtual WAN hub as integrated connectivity. Branch CPE devices build their vendor SD-WAN tunnels to it, and it peers with the hub router over BGP to share routes.
