-Azure VMware Solution is incompatible with AS-Path Prepend for redundant ExpressRoute configurations and doesn't honor the outbound path selection from Azure towards on-premises. If you're running two or more ExpressRoute paths between on-premises and Azure, and the listed [Prerequisites](#prerequisites) are not met, you may experience impaired connectivity or no connectivity between your on-premises networks and Azure VMware Solution. The connectivity issue is caused when Azure VMware Solution doesn't see the AS-Path Prepend and uses equal cost multi-pathing (ECMP) to send traffic towards your environment over both ExpressRoute circuits. That action causes issues with stateful firewall inspection.
