Distance Vector means that Routers are advertised as vector of distance and direction. 'Direction' is represented by next hop address and exit interface, whereas 'Distance' uses metrics such as hop count.
Routers using distance vector protocol do not have knowledge of the entire path to a destination. Instead DV uses two methods:
- Direction in which or interface to which a packet should be forwarded.
- Distance from its destination.

What is Distance Vector protocols?
Distance vector protocols are routing protocols that use the distance and direction to a destination network to make routing decisions. Examples include RIP (Routing Information Protocol) and EIGRP (Enhanced Interior Gateway Routing Protocol). These protocols share routing information with neighboring routers and update their routing tables based on the information received.
Why do link-state protocols converge faster than most distance vector protocols?
Distance vector protocols compute their routing tables before sending routing updates; link-state protocols do not.
What three routing protocols are distance vector routing protocols?
Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP) are two very popular Distance Vector routing protocols
What are the disadvantages of distance-vector routing protocols?
Distance-vector routing protocols have several disadvantages, including slower convergence times, which can lead to routing loops and inconsistent routing information during updates. They also require more bandwidth for routing updates, as they send the entire routing table at regular intervals. Additionally, these protocols are less scalable compared to link-state protocols, making them less suitable for larger networks. Finally, distance-vector protocols are more susceptible to routing table corruption due to malicious attacks or network errors.
When should distance vector routing be used?
Distance vector routing is used when the network is simple and has no hierarchical design. Examples of distance vector routing protocols are RIP and IGRP.

What is one fundamental difference between distance vector routing protocols and link state routing protocols?
Distance vector protocols exchange their routing tables, and add a metric to each route. Link-state routing protols exchange topology information, then calculate the routes. As a result, there are the following fundamental differences:The information that is exchanged - routing table vs. topology information.Link-state protocols know the topology of the network (or an area); distance vector routing protocols don't.When the best route is calculated: in distance-vector routing protocols, a metric is added while the route is propagated from router to router. In link-state protocols, the best route is calculated separately by each router, only after having complete topology information.
List the 2 classful routing protocols and explain the most serious limitation of these two protocols?
IGRP and RIPv1
What are the characteristics of a distance vector routing protocol?
Two Characteristics: RIP is an example of distance vector routing protocols. Updates are periodic and include the entire routing table
What best describes the operation of distance vector routing protocols?
They send their routing tables to directly connected neighbors.
