I agree with Kent.....  Although the link you (Rick) provided uses the word
"link-state", it uses it once in the opening and once in the summary...
That's it!  The fact is that one needs to analyze the protocol to see it's
behavior... it may well have traits of this or that type of protocol but not
be either one.....  I mean, really the categories of Distance-Vector and
Link-State are just descriptions, not hard boundaries.....

Priscilla has made a convincing argument that EIGRP acts mostly as a
Distance-Vector protocol.....  Although it has advanced features that may
resemble those of a link-state protocol, that doesn't make it link-state.
As she mentioned, Link-State means something very specific to mathematicians
(where all of these magic algorithms come from... *not* network people)...
Link-state machinesBut, again, as Kent says, if you disagree then lay out
your arguments for people to read and decide...

It's interesting to note that Distance-Vector protocols, because of their
operation, require various things to help them prevent routing loops, like
poison reverse and split-horizon.  EIGRP uses split-horizon, but not poison
reverse.  Does that make it distance-vector?  Not necessarily..... But it
doesn't mean it's not either =)   (I love riding the fence.. hehe)

Check out the following link, and compare what it says to EIGRP and see what
you think.....
