Why is it difficult for routing loops to occur in networks that use link-state routing?

  1. Each router builds a simple view of the network based on hop count.
  2. Routers flood the network with LSAs to discover routing loops.
  3. Each router builds a complete and synchronized view of the network.*
  4. Routers use hold-down timers to prevent routing loops.
