To create a route table

This example creates a route table for the specified VPC.

Command:

aws ec2 create-route-table --vpc-id vpc-a01106c2

Output:

{ "RouteTable": { "Associations": [], "RouteTableId": "rtb-22574640", "VpcId": "vpc-a01106c2", "PropagatingVgws": [], "Tags": [], "Routes": [ { "GatewayId": "local", "DestinationCidrBlock": "10.0.0.0/16", "State": "active" } ] } }
