2: Link-State IGP Migrations > 2.3 Case Study

2.3 Case Study

A fairly common real-life situation in which a networking engineer has to face a link-state IGP migration results from a company acquisition. There are many documented cases of the challenges and risks associated with a network merger, many of them even made public.

As a typical case study for link-state IGP migrations, imagine a company acquisition scenario. The multinational Internet service and content provider "Gale Internet" has decided to purchase networks and assets overseas to extend their service portfolio. With these strategic acquisitions, "Gale Internet" acquires stronger regional footprint to offer contents, Internet access and corporate-grade VPNs with each of these networks while interconnecting all of them with newer leased lines and infrastructure, now directly managed from the central location from "Gale Internet".
