The routing table exchange process is simulated by the distance vector routing algorithm, which demonstrates the changes of the routing table after each round of the switch, and dynamically generates the network topology graph,　the initial routing table, and the exchange routing table. Observation and discussion of how many rounds of exchange routing table stability.
