Simulation and Analysis of OSPFv2 Neighbor Authentication Based on GNS

Abstract:

Routing information release is a kind of promise from the router for network reachability. Illegal routing information may have disastrous effects on the normal work of the network. Open Shortest Path First (OSPF) protocol provides authentication methods to protect the authenticity and integrity of the routing traffic. This paper describes two authentication types of OSPFv2, analyzes the realization mechanism and packet header format of each authentication respectively. Based on GNS3, a typical network topology was designed, and with the aid of it we carried out functional verification and security analysis. The simulation can provide a reference for building an OSPF network. Experimental results show that the configuration of OSPFv2 routing authentication can effectively prevent the router from receiving unauthorized or malicious routing updates, thereby improving network safety.
