What Is AWS VPC Route Table?
An AWS VPC Route Table is a set of rules that determine where the network traffic from your subnet or gateway is directed. Each subnet (range of IP addresses in your VPC) is associated with a route table that controls the traffic flow between subnets. A route table has a destination address which determines where the network is directed. Route tables are essential when dealing with IPv4/IPv6 CIDR blocks, private or public subnets, network gateways, VPC endpoints, etc.
