Starting today, Amazon Transit Gateway supports intra-region peering, giving you the ability to establish peering connections between multiple Transit Gateways in the same Amazon Web Services China Region. With this change, different teams in your organization can deploy their own Transit Gateways, and easily interconnect them resulting in less administrative overhead and greater autonomy of operation.
Transit Gateway enables you to connect thousands of Amazon Virtual Private Clouds (VPCs) and your on-premises networks using a single gateway. Until now you could only establish peering connections between Transit Gateways in different Amazon Web Services regions. With this launch, you can simplify routing and inter-connectivity between networks that are serviced via separate Transit Gateways in the same Amazon Web Services region. The ability to natively peer Transit Gateways in the same region eliminates the need to create and manage transit VPCs, simplifies route-tables management, and reduces the probability of configuration errors. Using intra-region peering, you can build flexible network topologies and easily integrate your network with a third-party or partner managed network in the same region.
To get started, create a peering attachment on your transit gateway, and specify a transit gateway you want to peer within the same Amazon Web Services region. The peer transit gateway can be in your account or a different Amazon Web Services account. By creating static routes in Transit Gateway route tables, you can route traffic between the VPCs and connections attached to each Transit Gateway. This feature is available through the Amazon Management Console, the Amazon Command Line Interface (Amazon CLI), and the Amazon Software Development Kit (Amazon SDK).
Transit Gateway intra-Region peering is available in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD. Pricing for intra-region peering is the same as that for inter-region peering.
