Route Tables
A route table contains routes that determine where network traffic from a subnet is directed.
Why it matters
Without appropriate routes, resources may not reach the destinations they need.
How it works
Destination CIDR → target such as local, internet gateway or NAT gateway → associate route table with subnet.
Core Concept
Routes map destination ranges to targets such as local routing, an internet gateway or NAT gateway.
A subnet is associated with a route table that determines its routing behavior.
