What is used to facilitate hierarchical routing in OSPF?
- the use of multiple areas
- frequent SPF calculations
- the election of designated routers
Answers Explanation & Hints:
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.
