What is Azure Route Server used for?

It dynamically injects BGP routes from NVAs into VNet peering, enforcing traffic through firewalls without manual UDRs.

How do I set up Azure Route Server with Terraform?

Grab code from labs like gergovadasz.hu: define hub VNet, ARS resource, BGP peerings to NVA, spoke peers. Apply, BGP up.

Does Azure Route Server work with third-party NVAs?

Absolutely — Cisco, Palo Alto, FortiGate, even Linux iptables. Just enable BGP peering.
