Question

Exhibit

Options

• AAdd both Associations and Propagations in the second TGW route table.
• BDelete the both Connect and Transport attachments from the first TGW route table
• CAdd a static route in the Routes section
• DIn the second route table: create a propagation with the Connect attachment.

• A
  16% (7)
• B
  5% (2)
• C
  7% (3)
• D
  72% (31)

Explanation

The error message indicates that the Connect attachment is already associated with another transit gateway route table. You cannot associate the same attachment with more than one route table. However, you can propagate the same attachment to multiple route tables. Therefore, to fulfill your requirement of configuring a second route table for east-west traffic inspection between two VPCs, you need to create a propagation with the Connect attachment in the second route table. This will allow the second route table to learn the routes from the Connect attachment and forward the traffic to the security VPC. You also need to associate the second route table with the Transport attachment, which is the transit gateway attachment for the security VPC.
