Link-State Routing Protocol
 


 

2.1.1


Overview of link-state routing
 








Link-state routing protocols perform in
a very different way from distance vector protocols. Understanding
the difference between distance vector and link-state protocols is vital
for network administrators. One essential difference is that distance
vector protocols use a simpler method of exchanging routing information.
Figure
outlines the characteristics of both distance vector and link-state
routing protocols.Link-state
routing algorithms maintain a complex database of topology information.
While the distance vector algorithm has nonspecific information about
distant networks and no knowledge of distant routers, a link-state
routing algorithm maintains full knowledge of distant routers and how
they interconnect.
