What is a benefit of multiarea OSPF routing?
- Topology changes in one area do not cause SPF recalculations in other areas.
- Automatic route summarization occurs by default between areas.
- Routers in all areas share the same link-state database and have a complete picture of the entire network.
- A backbone area is not required.
Answers Explanation & Hints:
With multiarea OSPF, only routers within an area share the same link-state database. Changes to the network topology in one area do not impact other areas, which reduces the number of SPF algorithm calculations and the of link-state databases.
