Q

What is a link state routing protocol ?

A

Uses link-state information received from routers to create topology map/ select best path to all destination networks in the topology

16
Q

Advantages of Link-State Protocols

A

Faster convergence

Each router builds its own topological map of the network

17
Q

Disadvantages of LSP

A

More memory requirements
More CPU processing requirements
Affects bandwidth during LCP flooding.

18
Q

What loop prevention technique is implemented by distance vector routing protocols?

A

Split horizon

19
Q

What are OSPF Hello packets for ?

A

They are used to maintain neighbor relationships

They are used for dynamic neighbor discovery.

20
Q

What are two characteristics of link-state protocols compared to distance vector protocols?

A

require a lot of hardware resources

compute their own knowledge of the network topology.

21
Q

Which routing protocol is designed to use areas to scale large hierarchical networks?

A

OSPF
