AWS Outposts racks support multiple LGW routing domains

AWS Outposts Racks Update

AWS Outposts racks now support multiple local gateway (LGW) routing domains, allowing you to create up to 10 isolated routing domains per Outpost with independent route tables and BGP sessions to your on-premises network. This feature enables traffic separation between routing domains and supports both customer-owned IP (CoIP) and direct VPC routing (DVR) modes on the same Outpost.

With this update, you can segment on-premises network connectivity for different departments or business units sharing an Outpost. Each routing domain maintains its own LGW VIF Group, LGW Route Table, and VPC associations, preventing traffic from crossing between domains. Configuration can be done through the AWS Management Console or AWS CLI.
