Zorluk: OrtaRouting Concepts and Dynamic Routing Protocols

A network administrator is evaluating dynamic routing protocol characteristics for an enterprise LAN deployment. Which of the following operational features are specific to link-state routing protocols such as OSPF when compared to distance-vector routing protocols? (Select TWO.)

  1. Routers build and maintain a complete network topology map in a centralized or local Link-State Database (LSDB).Cevap
  2. B
    Routers transmit their full routing table to all directly connected neighbors on a continuous periodic timer.
  3. Routing update messages are triggered and flooded only when a state change occurs on a link.Cevap
  4. D
    Path selection relies primarily on hop count to measure the distance to a destination network.

Cevap

Link-state protocols maintain a full network topology map in a Link-State Database (LSDB) and use event-driven triggered updates when link status changes occur.
Link-state protocols require routers to accumulate a complete view of the network topology inside a Link-State Database (LSDB) and use triggered LSA updates whenever network interface states change.

Adım Adım Çözüm

1
Analyze link-state topology mapping.
Link-state routers collect Link-State Advertisements (LSAs) to build an identical map of the entire network area in their Link-State Database (LSDB).
This complete visibility allows the Shortest Path First (SPF) algorithm to calculate optimal loop-free paths.
2
Evaluate routing update transmission methods.
Link-state protocols issue differential updates only when a link state changes, rather than continuously transmitting the entire routing table.
Triggered updates minimize unnecessary bandwidth consumption and speed up network convergence.
