What is Azure Route Server?

Azure Route Server dynamically injects BGP routes from NVAs into VNet tables, automating hub-spoke traffic enforcement without UDRs.

How to set up Azure Route Server with Terraform?

Deploy in hub subnet, enable BGP, peer with NVA, peer spokes to hub — Terraform handles the rest via azurerm_route_server resource.

Does Azure Route Server work with third-party NVAs?

Yes, Palo Alto, FortiGate, Cisco — as long as BGP peers up. Test ASNs and MTU first.
