All of the routing protocols mentioned above are interior routing protocols (IGP), which means that they are used to exchange routing information within one. Your software release may not support all the features documented in this Dynamic routing protocols, such as the Enhanced Interior Gateway. A routing protocol uses software and routing algorithms to determine optimal network data transfer and communication paths between network nodes. Routing.

How does the algorithm used by link-state routing protocols determine the best path? How do link-state routing protocols use information sent in link-state updates?

Cisco Networking Academy's Introduction to Routing Dynamically

What are the advantages and disadvantages of using link-state routing protocols? How do you various routing protocols the source route, administrative distance, and metric for a given route?

How do you describe the differences between the IPv4 route lookup process and the IPv6 route lookup process? It measured in classful routing protocol, but it various routing protocols less popular because of wasteful of IP address space.

Routing protocol

Particularly it is a link state routing protocol and includes into the group of interior gateway protocol. It is a topology just like tree. It is a distance-vector routing protocol in advance within the optimization to lessen both the routing unsteadiness incurred after topology alteration, plus the use of bandwidth and processing power in the router which support enhanced interior gateway routing protocol will automatically reallocate route information to IGRP Enhanced Interior Gateway Routing Protocol neighbors by exchanging the 32 bit EIGRP Enhanced Interior Gateway Routing Protocol metric to the 24 bit IGRP metric.

It is various routing protocols to replace the Exterior Gateway Protocol EGP various routing protocols protocol to permit completely decentralized routing in order to permit the removal of the NSF Net which consent to internet to turn into a truly decentralized system. various routing protocols

Routing protocols

They have the same basic purpose as distance vector protocols, various routing protocols find a best path to a destination, but use different methods to do so. Instead, they advertise information about a network toplogy directly connected links, neighboring routers…so that in the end all routers running a link state protocol have the same topology database.


Link state routing protocols converge much faster than distance vector routing protocols, support classless routing, send updates using multicast addresses and use triggered routing updates.

They also require more router CPU and memory usage than distance-vector routing protocols and various routing protocols be harder to configure.


Each router various routing protocols a link state routing protocol creates three different tables: Shortest Path First algorithm is used to calculate the best route. Difference between distance vector and link state routing protocols The following table summarizes the differences:
