Separate TGW Route Table for each TGW attachment
- A can connect to B
- A can connect to C
- B can connect to A
- B can connect to C
- B can connect to D
- C can connect to A
- C can connect to B
- D can connect to B

RTB1 has an association with A, B, and C and propagation of the same too.
so you don't have route from B to D
RTB2 has an association with B and D and propagation of the same B and D
This is not possible. Because TGW Attachment can be associated only with one TGW Route Table
If you try to associate the second one, you will get an error:
There was an error creating your transit gateway route table association.
Transit Gateway Attachment tgw-attach-0fc***** is already associated to a route table.
The simplest way for you would be to have a separate TGW Route table for each TGW attachment and each Route Table would have only the necessary routes

My apology. RTB2 has only an association of D but the propagation of B and D.

Have you added the routes in the route tables of B and D to route traffic back to the TGW attachment?
