Create 3 VPC's
Create 2public & 2private subnets in different availability zones for all VPC's
Add those subnets to respective route tables
Create internet gateways for each VPC's & attach it to VPC
Route the IG to public RT
Create peering connection
Add it in the Route table
Now ping to private instance of other VPC & it will ping
2] Create transit gateway and connect 3 VPC, check transitive connection here
Create Transit gateways
Create Transit gateway attachments
you can see the changes in the Transit gateway route tables
Editing the main route tables of the instances and attaching tgw attachments

Interface Endpoint
Network interface will be created after doing all this
