>From TCP/IP vol 1 p261 "EIGRP is occasionally described as a distance vector protocol that acts like a link-state protocol. ...a distance vector protocol shares everything it knows but only with directly connected neighbors. Link-state protocols announce information only about their directly connected links, but they share the information with all routers in their routing domain or area."
Also (my thoughts, not the book's) consider that EIGRP route selection is based on items such as feasible -distance- and reported -distance- and you can see how EIGRP cares about much more than the status and cost of individual links alone. Distance is just a metric - RIP uses hops, EIGRP uses a convoluted formula - and distance is key to how EIGRP functions.

To: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" ?EIGRP? is a hybrid ( Link state + distance vector ) , Link state i understand as when there is any topology change it will send triggered?updates.. but?is it distance?vector ? _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
