Yes Split-horizon is used in link-state routing protocols.. I would have
thought differently due to that all linkstate routers have the same link
state database and use that to choose the routes from there but here is a
link showing using split-horizon with OSPF.

I guess my question boils down to this: is split-horizon only used for
distance vector protocol? ( I have received several contradicting
information on this point!)

No it seems like you understand but I don't think your comments have
anything to do with what is on page 14-27 unless I'M missing something... I
dont' have the book but from you excerpt I don't understand how your
comments / question has to do with the excerpt except they both have the
words split horizon. Could you explain?
Thanks
Cory

Subject: Frame Relay Split Horizon NBMA
On page 14-27 on the Cisco ICND manual, it is written that one will have
reachability issues if one is using:
*a distance vector routing protocol
*partial meshed network
*NBMA frame relay model
*split horizon enabled on the routing protocol.
My understanding is that split horizon will prevent routes to be adverstised
on the same interface from which they were learned. This should apply
regardless of whether the routing protocol is using broadcastd (distance
vector), multicasts or unicasts (link state and hybrid routing protocols)!
Am I missing something?
