This thesis studied the implementation of FRRouting in Proxmox to create a spine-and-leaf architecture-based data centre design that would have BGP-EVPN introduced into servers. The aim was to create a small-scale data centre, which would have the benefits of modern techniques to scale and use of VXLAN for communication.

A virtual laboratory was used to take the approach of design research, where various iterations were tested and experimented on to gather data. Having simulated the network, observation of behaviour and researching implementation of necessary software was made possible. In this way, it resembled the experiential learning theory. In addition, research into literature sources related to spine-and-leaf -design was done along with studying the various software used.

In the conclusion of this thesis, it was found that implementing FRRouting made it possible to design a small-scale data centre, where the leaf -component was included into the server nodes rather than onto a separate physical switch. This meant that Proxmox -server could be harnessed to participate directly in BGP-EVPN and have its own VXLAN -interfaces.

This allowed the formulation of a design, based on spine-and-leaf architecture, which utilized BGP-EVPN for VXLAN -capabilities. With the design, an installation guide that documented findings regarding implementation of FRRouting on Proxmox was produced with this design. Through these two documents, the thesis achieved the goal of producing a design of a small-scale data centre that utilizes the modern spine-and-leaf architecture.
