question:distance vector routing protocol instead of a link state routing protocol.

Hello.

I am a student and would like to have an answer to the question: Report three cases where you would choose a distance vector routing protocol instead of a link state routing protocol.

Thank you very much

Hello,

 

1. You merge two networks and one network has a distance vector routing protocol (e.g. RIPv2) configured and cannot change that.

2. Your routers have very imited resources and can only run distance vector.

3. Your network engineers have only limited knowledge about designing and implementing link state protocols, hence they chose to use distance vector.

Hi @anna84,

 

One case:

 

OSPF(link state) is a much heavier and slower protocol than EIGRP(distance vector).

When a change in the topology occurs, EIGRP only informs the neighbors, but OSPF alters the database of all the routers and proceeds to recalculate the routes with the SPF protocol. The routing updates, therefore, are much larger than in EIGRP.

 

Regards
