The infrastructure of Internet routing for network infrastructure protection is discussed. For routing, the infrastructure is divided into two main domains which include intra-domain and inter-domain. The entire routing infrastructure is a collection of intra-domain routing regions connected through an inter-domain routing functionality. A particular intra-domain routing environment called as Autonomous System (As), is administered by a specific administrative authority, which usually owns the routers in its domain. Most common routing protocols in an AS are Open Shortest Path First (OSPF) and Intermediate-System-to-Intermediate-System (IS-IS) routing protocols. Routing protocols can cause malfunctions of the entire routing domain, as routers are network-layer devices. If routers in a particular autonomous system are compromised, then it can affect transit traffic between different domains using the AS for reachability.
