AWS Outposts racks support multiple LGW routing domains

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

With multiple LGW routing domains, 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. You can configure multiple LGW routing domains through the AWS Management Console or AWS CLI.

Multiple LGW routing domains is available on second-generation Outposts racks at no additional charge. See the FAQs for Outposts racks for the latest list of supported AWS Regions.
