Just because EIGRP has some of the advantages of a link-state protocol doesn't
mean it is, even partially, a link-state protocol. From Doyle, p327...
"EIGRP is, as the name says, an enhancement of IGRP... EIGRP remains a distance
vector protocol... EIGRP is occasionally described as a distance vector
protocol that acts like a link state protocol". Various other sections explain
how it has some advantages of a link-state protocol, but Doyle is very clear
that EIGRP is distance vector, not link state, and explains why.
With regards to the original OSPF question, I can't see how split horizon would
apply to a link-state protocol. I can't find any reference to an OSPF
split-horizon command (but if somebody has a URL I'd be interested to see what
it says). I'm not positive, but I don't think split-horizon would be applicable
to OSPF.

I never said it was a link-state protocol. I said it was a hybrid, and that
it was link-state AND distance-vector.

"Enhanced IGRP (EIGRP) is a Cisco proprietary protocol that combines
the advantages of link-state and distance-vector routing protocols. As a
hybrid protocol it includes the following features...."
Proof is in the pudding. Love your book by the way... ;)
