Routing tables are an essential component in managing VPC-to-VPC communication within AWS. A routing table is a set of rules that determine how network traffic is directed within a VPC.

In AWS, a VPC has a default routing table associated with it, and you can also create custom routing tables for more granular control over traffic routing.

Each routing table contains a list of routes, with each route specifying a destination and target. When a packet of network traffic arrives at a VPC, the routing table is consulted to determine the next hop for the packet based on its destination.

For example, if you have multiple VPCs and want to enable communication between them, you would configure the routing tables in each VPC to include routes that point to the appropriate VPC peering connections.

Routing tables play a crucial role in enabling VPC-to-VPC communication within AWS. They dictate the paths that network traffic takes, ensuring that it reaches its intended destination.

To enable communication between VPCs using VPC peering, you would add ____ route entries to the routing tables in each VPC that point to the appropriate VPC peering connections.
