Accepted Answer

Hi,

This [blog](https://aws.amazon.com/blogs/mt/scale-multi-account-architecture-aws-network-firewall-and-aws-control-tower/) discusses similar architecture with TGW + Centralized Networking account and Control Tower.

This [whitepaper](https://docs.aws.amazon.com/whitepapers/latest/building-scalable-secure-multi-vpc-network-infrastructure/centralized-access-to-vpc-private-endpoints.html) has reference architectures for TGW hub & spoke deployment.

You can explore the [TGW workshop](https://controltower.aws-management.tools/networking/tgw/tgw-simple/)

Also, Please refer to this [https://aws.amazon.com/blogs/architecture/field-notes-working-with-route-tables-in-aws-transit-gateway/]()
It explains the packet flow with multiple Transit gateway route table in centralized account (Network account) and how you can seggerate the traffic.
