connecting-vpcs-with-peering

What problem does it solve?

This Skill solves the challenge of enabling private network connectivity between two AWS VPCs by correctly creating and configuring VPC peering, including routes, DNS resolution, and cross-VPC security group guidance.

Core Features & Use Cases

• Peering lifecycle management: Creates the VPC peering connection, waits for it to become active, and handles same-account auto-accept vs cross-account manual acceptance.
• Route table updates across both VPCs: Validates CIDR overlap, then updates all route tables in both VPCs so traffic can flow to the peer CIDRs through the peering connection.
• DNS resolution and hostname enablement: Configures peering DNS options on both sides to ensure name resolution works as expected across VPC boundaries.
• Security group recommendations: Provides actionable guidance to permit cross-VPC traffic safely (without overly permissive rules).

Quick Start

Use the connecting-vpcs-with-peering skill to establish peering between requester_vpc_id vpc-12345678 and accepter_vpc_id vpc-87654321 by updating routes, enabling DNS resolution across the peering, and providing security group rules for cross-VPC connectivity.
