Question:
What is used to facilitate hierarchical routing in OSPF?

  • the use of multiple areas
  • frequent SPF calculations
  • autosummarization
  • the election of designated routers

Explanation: OSPF supports the concept of 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.
