:::: OSPF and BGP ::::

  Advanced OSPF & BGP Interview Questions & Answers - Mock Q&A Format Question 1: What are the different types of OSPF packets and their usage? Answer: Hello Packet : Initiates and maintains neighbor relationships (contains Router ID, Hello/Dead intervals). DBD (Database Description) : Summarizes LSDB, exchanged during Exstart/Exchange. LSR (Link State Request) : Requests specific LSAs. LSU (Link State Update) : Sends full LSA details. LSAck (Link State Acknowledgment) : Acknowledges receipt of LSAs. Question 2: How does OSPF prevent loops? Answer: OSPF uses  Dijkstra’s SPF algorithm  to calculate shortest paths. Intra-area: Each router maintains identical LSDBs, preventing loops. Inter-area: ABRs do not advertise LSAs back into the area from which they were received (split-horizon like behavior). Question 3: What are stub areas in OSPF? Answer: Stub Area : Allows LSA 1, 2, 3; blocks LSA 5. Totally Stubby Area : Allows only LSA 1 and 2; blocks 3, 5 (Cisco prop...
