## Overview

This repository is a catalog of 13 enterprise routing and WAN lab scenarios, not an application with a shared runtime. The learner workflow is to choose a documented scenario, use its IOS configurations and Packet Tracer project, and practice or verify the network behavior in a simulator. The README documents all scenario capabilities; no source excerpts were provided, so the graph does not infer internal device-level call or traffic flows.

Main entry points: [`01-dynamic-routing-eigrp/README.md`](https://github.com/abdulwahabsaim/enterprise-routing-labs/blob/main/01-dynamic-routing-eigrp/README.md) (EIGRP Routing), [`02-dynamic-routing-multi-area-ospf/README.md`](https://github.com/abdulwahabsaim/enterprise-routing-labs/blob/main/02-dynamic-routing-multi-area-ospf/README.md) (Multi-Area OSPF), [`08-ospf-neighbor-troubleshooting-lsdb/README.md`](https://github.com/abdulwahabsaim/enterprise-routing-labs/blob/main/08-ospf-neighbor-troubleshooting-lsdb/README.md) (OSPF Troubleshooting), [`13-dynamic-routing-eigrp-variance/README.md`](https://github.com/abdulwahabsaim/enterprise-routing-labs/blob/main/13-dynamic-routing-eigrp-variance/README.md) (EIGRP Variance)
