Attach Edge Gateway to Transit Gateway

You can attach an Edge Gateway to multiple Transit Gateways. Each attachment can be configured with different parameters, such as connecting interfaces, connection over private or public network, high-performance encryption, and Jumbo Frame.

To create a High Performance Encryption mode attachment, make sure the Transit Gateway is created with High Performance Encryption enabled.
If you want Jumbo Frame enabled on the Edge Gateway, make sure to enable Jumbo Frame on the Edge Gateway before you attach it to the Transit Gateway.
