OSPF اسئلة واجوبة المقابلات
سؤال 11. What is OSPF metric, and how is it calculated?
OSPF metric is cost, which is inversely proportional to bandwidth. The formula is cost = 10^8 / bandwidth (in bps).
سؤال 12. Explain OSPF DR/BDR election process.
On multi-access networks, OSPF routers elect a Designated Router (DR) and a Backup Designated Router (BDR) to reduce OSPF routing traffic.
سؤال 13. What is OSPF adjacency?
OSPF adjacency is a relationship formed between OSPF routers to exchange routing information. It is established through the OSPF hello protocol.
سؤال 14. How does OSPF handle network convergence in the presence of a link failure?
OSPF quickly reacts to link failures by recalculating the SPF tree and updating routing tables. This fast convergence is facilitated by OSPF hello and dead interval timers.
سؤال 15. What is the OSPF LSAge timer?
The LSAge timer in OSPF is used to age out LSAs from the LSDB. If an LSA's age exceeds its maximum age, it is considered expired and removed from the LSDB.
