FAQPage Schema

How do I design a highly available Azure ExpressRoute architecture with multiple circuits?▼

Azure ExpressRoute architecture for high availability uses multi-circuit routing and BGP peering to ensure redundancy. This guidance covers design patterns that prevent single points of failure across regional deployments.

What is the best way to configure BGP peering for an ExpressRoute circuit?▼

Configuring ExpressRoute BGP peering requires following established design patterns for routing optimization. This ensures stable route propagation and appropriate traffic engineering across your peering connections.

Can I use Azure ExpressRoute with Site-to-Site VPN for failover coexistence?▼

Yes, Azure ExpressRoute can coexist with S2S VPN for failover scenarios. This architecture pattern provides backup connectivity, allowing traffic to route through the VPN tunnel if the primary circuit fails.

How do I troubleshoot ExpressRoute connectivity and routing failover issues?▼

Troubleshoot ExpressRoute connectivity by running operational checks across circuits, gateways, and peering. This diagnostic process identifies routing mismatches, failover gaps, and BGP configuration errors impacting performance.

When should I use ExpressRoute Global Reach and Direct deployment across regions?▼

Use ExpressRoute Global Reach and Direct deployment when connecting on-premises networks across multiple regions without traversing the public internet. This approach optimizes bandwidth and reduces latency for cross-region traffic.

Do I need specific RBAC and monitoring configurations for Azure ExpressRoute operations?▼

Yes, specific RBAC and monitoring configurations are needed for secure Azure ExpressRoute operations. This guidance provides maintenance workflows and encryption settings to maintain operational stability and security compliance.
