1

Routers exchange information about routes using different methods

2

but as an example, OSPF uses link-state updates

3

to advertise information about routes that are available in the network topology.

4

This puts overhead on the network because additional traffic is sent

5

and received by routers as they communicate with 1 another.

6

However, as the network grows there’s an exponential increase in the amount of work

7

that would be required if static routes where used

8

and thus because of the advantage that dynamic routing protocols

9

put less overhead and workload on administrators to maintain routing tables

10

they are used in most networks today especially larger networks

11

with the largest being the internet which runs on BGP or Border Gateway Protocol

12

and once again dynamic routing protocols can adjust to changes

13

in the topology automatically and without administrator intervention.
