eigrp

I always thought that neighbors formed in EIGRP were not necessarily directly connected because the only requirement for two routers to be neighbors is that they share the same Autonomous System and K-values, but it seems that I was wrong. I have looked up several books, they do not seem to give a clear answer.

And I am even more confused with OSPF...

Please, give me some light here. Thank you.
