Route Table

in AWS, each subnet can only be associated with one route table at a time. Here's how it works:

Single Route Table per Subnet: If you need different routing rules for different parts of your network, you need to create multiple subnets and associate each with a different route table.
Multiple Subnets per Route Table: Conversely, a single route table can be associated with multiple subnets. This is useful when you want multiple subnets to share the same routing configuration.
