Administering OSPF Routing

This chapter describes commands you can use to configure Open Shortest Path First (OSPF) routing on your system. Configuring and managing OSPF routing involves:


Menu Structure

The commands that you can use depend on the system that you have, your level of access, and the types of modules and other hardware options that are configured for your system. The following diagram shows the complete list of commands for all systems. See the checklist at the beginning of each command description in this chapter for whether your system supports the command.
