Re: Difference between Distance vs Link state protocol

distance vector...routing by rumour priciple
link state ............highly accurate

distance vector....broadcasts
link state multicast..

no support for distace vector in MPLS TE as router dont have full picture of
topology ..

limit on number of routers in distance vector

no limit in no of routers in ospf ..as link state follows hirarchial design.

distace vector ..easy to set up and manage ..

link state requires different conditions. ..such as all areas must be
connected to backbone.
 timers should match .....netwok type should match ..stub area flag should
match ....area id should match..
