OSPF 面试题与答案
问题 6. What is the OSPF SPF algorithm?
SPF (Shortest Path First) is the algorithm used by OSPF to calculate the shortest path tree and determine the best routes in the network.
问题 7. Differentiate between OSPF areas and autonomous systems.
OSPF areas are subdivisions of an OSPF autonomous system. An OSPF autonomous system is a collection of OSPF areas connected by a backbone area (Area 0).
问题 8. Explain OSPF LSA types and their functions.
OSPF LSAs (Link State Advertisements) include Router LSAs, Network LSAs, Summary LSAs, ASBR Summary LSAs, and External LSAs, each serving a specific purpose in the OSPF network.
问题 9. How does OSPF handle equal-cost paths?
OSPF allows for load balancing across equal-cost paths by installing multiple routes in the routing table.
问题 10. What is OSPF convergence time?
Convergence time is the duration it takes for OSPF routers to update their routing tables after a topology change. OSPF typically has fast convergence due to its incremental SPF algorithm.
