This research project explores the operation of the IS-IS routing protocol, as well as DHCP and DNS services provided by a Raspberry Pi computer. IS-IS is a routing protocol that is commonly ignored in most training and certification programs, because it is most frequently used by service providers. However, IS-IS solutions are also deployed in some large enterprise networks, making experience with the protocol a valuable skill.
In order to gain a deeper understanding of the routing domains, route propagation, and general operation of IS-IS, additional services were implemented in this project. A Raspberry Pi computer was used as an internal DHCP and DNS server for all hosts in all domains and areas of the network. This network design facilitated learning and increased network troubleshooting skills
