How matteogradinaru/isp-and-enterprise-network works
This repository is a documentation-and-configuration lab, not an executable software application. An engineer uses the Cisco IOSv configurations in GNS3 to explore two documented network designs: dual-ISP routing with VRF-Lite, and an MPLS service-provider backbone with tenant VPNs and IPsec. The root README documents the capabilities and protocol relationships; the tree identifies device configuration sets. Device-to-device links are omitted because no topology wiring was provided, and the individual configurations were not sampled.
