Abstract [en]

This work has been carried out at a company in the region which has about 30000 employeeswith about 400 sites all over the world. The company outsources their network including theLAN refresh and the WAN migration. They needed help with an upgrade of their LAN at theirScandinavian headquarters and to find a new solution for their WAN. The reason why the upgradeof the LAN was needed was that the equipment was too old and did not pass the securityrequirements. They also required a solution to segment their LAN, which consisted of a singlelarge VLAN with 1,300 employees. their WAN solution was made up of tunnels between all officesand the headquarter were used as the central point. They wanted to get away from beingdependent on a central point while redundancy was not always working as it should.The solution to the WAN problem was to use the ISPs backbone based on MPLS. There are two mainsolutions, layer 2 (Ethernet) VPN or layer 3 (IP) VPN. In the case of IP VPN, there are a couple of differentconnectivity options such as a static route, or use a routing protocol (eg OSPF or BGP). The final solutionwas IP VPN with OSPF as routing protocol to the ISP. With regard to the configuration of the OSPF solutionwas that every office became an own OSPF domain, configured with area 0. The report also includesthe implementation of the WAN migration with its problems.The upgrade of the LAN was a lot of planning, documentation and security. The solution for the segmentationwas to create a VLAN per floor. Because of the new software they can have the required securityfeatures.
