Link State Routing Analysis

This question asks to identify the true statements regarding link-state routing protocols.

Statement A: False. The "count-to-infinity" problem is associated with Distance Vector routing, not Link State routing. Link state routing avoids this issue by having a complete network map.
Statement B: True. Link state protocols like OSPF use flooding to distribute Link State Packets (LSPs) efficiently to all routers within the network or area.
Statement C: True. Each router is responsible for creating its own Link State Packet (LSP), which contains information only about its local links and their status (cost, neighbors).
Statement D: True. After the LSPs are flooded and processed, all routers within the same routing domain possess an identical link state database, reflecting the complete network topology.
Statement E: False. Link state routing uses algorithms like Dijkstra's shortest path algorithm to calculate the shortest paths based on the constructed link state database. It does not use distance vector routing principles for path calculation.
