What are the advantages and disadvantages of the three types of routing tables?

The three types of routing tables are fixed, dynamic, and fixed central. The fixed table must be manually customized every time there is a change. A dynamic table alter its information based on network traffic, decreasing the amount of manual maintenance. A fixed central table lets a manager change only one table, which is then read by other devices. The fixed central table decrease the need to update each machine's table, as with the fixed table. Usually a dynamic table causes the fewest problems for a network administrator, although the table's contents can alter without the administrator being aware of the change.
