As a key device in the Internet, routers and L3 switches have been widely used. As people have high requirements on the quality of network services, the functions and performance indicators of routers and L3 switches become more and more important. Route tests include consistency tests, interoperability tests, functional tests, and performance tests. The routing protocol simulation is the basis of the routing protocol. Among the many routing protocols, OSPF is the most complex, and the simulatio
