Hey Taqdir,

As I understand it EIGRP uses "Distributed Update algorithm" or "DUAL", 
in combines the link-state and distance-vector algorithms.  Routers 
running EIGRP choose paths based on vector (a direction) and distance 
but convergence is managed by change based updates.  Together the two 
are combined in the DUAL algorithm to provide convergence speeds as fast 
(some say faster than) link state protocols without the computational 
and storage overhead.

If I'm wrong please correct me.
