How to Create & Configure Route Table on Amazon Web Service(AWS).

A route table contains a set of rules, called routes, that are used to determine where network traffic from your subnet or gateway is directed.

The route table contains existing routes with targets other than a network interface, Gateway Load Balancer endpoint, or the default local route. The route table contains existing routes to CIDR blocks outside of the ranges in your VPC. Route propagation is enabled for the route table.
