2.3.3. Azure Route Server
Azure Route Server enables dynamic routing between your network virtual appliances (NVAs) and Azure's virtual network routing.
💡 First Principle: Azure Route Server doesn't route traffic—it exchanges routes. It speaks BGP with your NVAs and injects their routes into your VNet, eliminating manual UDR management.
Key Capabilities:
- BGP peering with NVAs (up to 8 peers)
- Automatic route propagation to VNet subnets
- Branch-to-branch transit for SD-WAN scenarios
- Route exchange between ExpressRoute and VPN
When to Use:
- SD-WAN appliances that need to advertise routes
- Active-active NVA deployments
- Complex routing with multiple on-premises sites
