Associating a Route Table with a Subnet
Scenarios
After a subnet is created, the system associates the subnet with the default route table of its VPC. If you want to use specific routes for a subnet, you can associate the subnet with a custom route table.
The custom route table associated with a subnet affects only the outbound traffic. The default route table determines the inbound traffic.

After a route table is associated with a subnet, the routes in the route table control the routing for the subnet and apply to all cloud resources in the subnet.
