The following diagram shows a transit gateway with three VPC attachments. The route table for each of these VPCs includes the local route and routes that send traffic destined for the other two VPCs to the transit gateway. The following is an example of a default transit gateway route table for the attachments shown in the previous diagram. The CID...
A transit gateway attachment is both a source and a destination of packets. You can attach the following resources to your transit gateway:
AWS Transit Gateway supports Equal Cost Multipath (ECMP) routing for most attachments. For a VPN attachment, you can enable or disable ECMP support using the console when creating or modifying a transit gateway. For all other attachment types, the following ECMP restrictions apply:
When you attach a VPC to a transit gateway, you must enable one or more Availability Zones to be used by the transit gateway to route traffic to resources in the VPC subnets. To enable each Availability Zone, you specify exactly one subnet. The transit gateway places a network interface in that subnet using one IP address from the subnet. After you...
Your transit gateway routes IPv4 and IPv6 packets between attachments using transit gateway route tables. You can configure these route tables to propagate routes from the route tables for the attached VPCs, VPN connections, and Direct Connect gateways. You can also add static routes to the transit gateway route tables. When a packet comes from one...
A transit gateway enables you to attach VPCs and VPN connections and route traffic between them. A transit gateway works across AWS accounts, and you can use AWS RAM to share your transit gateway with other accounts.
AWS Transit Gateway Connect enables native integration of Software-Defined Wide Area Network (SD-WAN) appliances into AWS. Customers can now seamlessly extend their SD-WAN edge into AWS using standard protocols such as Generic Routing Encapsulation (GRE) and Border Gateway Protocol (BGP).
