Which is better distance vector or link state?

Distance vector protocols are generally easier to configure and require less maintenance than link state protocols. On the downside, distance vector protocols do not scale well because they require higher CPU and bandwidth utilization. They also take longer to converge than do link state protocols.

What is distance vector in distance vector routing algorithm?

Distance Vector Algorithm – A router transmits its distance vector to each of its neighbors in a routing packet. Each router receives and saves the most recently received distance vector from each of its neighbors.

Is BGP distance vector?

“Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information between autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol.”

Is OSPF a path vector?

Although OSPF operates as a link-state routing protocol within an area, its behavior between areas is predominantly distance vector.

What are the advantages of distance vector routing?

Advantages

• Distance vector routing protocol is easy to implement in small networks. Debugging is very easy in the distance vector routing protocol.
• This protocol has a very limited redundancy in a small network.

What are the two main elements of distance vector routing?

Routing Table

• NET ID: The Network ID defines the final destination of the packet.
• Cost: The cost is the number of hops that packet must take to get there.
• Next hop: It is the router to which the packet must be delivered.

Is OSPF distance vector?

OSPF is not a distance-vector protocol like RIP, but a link-state protocol with a set of metrics that can be used to reflect much more about a network than just the number of routers encountered between source and destination. In OSPF, a router attempts to route based on the “state of the links.”

What is distance vector routing protocol?

Distance Vector Routing Protocol ( DVRP ) Definition – What does Distance Vector Routing Protocol (DVRP) mean? Distance Vector Routing Protocol (DVRP) is one of two major routing protocols for communications methods that use data packets sent over Internet Protocol (IP).

What is the link state algorithm?

The Link state routing algorithm is also known as Dijkstra’s algorithm which is used to find the shortest path from one node to every other node in the network.

What are common routing protocols?

Common routing protocols include RIP, RIPv2, IGRP, EIGRP, IS-IS and BGP. For the CCNA exam you will need to be well versed in RIP, RIPv2, IGRP and EIGRP. You should be aware of IS-IS and BGP, and be able to configure basic OSPF .

What is a link state routing protocol?

Link-state routing protocol. Link-state routing protocols are one of the two main classes of routing protocols used in packet switching networks for computer communications, the other being distance-vector routing protocols.
