The Internet routing system is responsible for maintaining consistent reachability information across the myriads of routers that make up the global network. The routing system adopts a two level hierarchy where individual organizations run Intra-domain Routing Protocols (IGPs) inside their Autonomous Systems (ASes) to manage internal router-level maps for their own domain. Meanwhile, there is a globally distributed Exterior Gateway Protocol (EGP) that is responsible for distributing AS-level reachability information across domains.

A crucial building block of this hierarchy is Route Redistribution, whereby routing information learned via one routing protocol (say, the EGP) is redistributed into another routing protocol (say, the IGP). This way ensuring global visibility of IP prefixes across the whole network. Unfortunately, despite tens of years of operational experience route redistribution is still not a solved problem.

In the thesis a test network will be simulated and setup to measure the performance of the network devices, for example routers, when receive and distribute Internet IP prefixes into a private network, as can be enterprise network or university network. Thus, the measurement of the features will be done with different protocols, and different amount of IP prefixes to know which of them requires more powerful devices to do their duties with acceptable performance.
