Which of the following is used to facilitate hierarchical scaling in OSPF?

  • Autosummarization
  • Frequent SPF calculations
  • The election of designated routers
  • The use of multiple areas

Explanation: OSPF supports the concept of using areas to prevent larger routing tables, excessive SPF calculations, and large LSDBs. Only routers within an area share link-state information. This allows OSPF to scale in a hierarchical fashion with all areas that connect to a backbone area.
