Re: Split horizon in OSPF???

Ok the RFC does go into how OSPF uses split-horizon. "
RFC3509 - Alternative Implementations of OSPF Area Border Route

OSPF prevents
   inter-area routing loops by implementing a split-horizon mechanism,
   allowing ABRs to inject into the backbone only Summary-LSAs derived
   from the intra-area routes, and limiting ABRs' SPF calculation to consider
   only Summary-LSAs in the backbone area's link-state database."

But where on the doc cd does it state that OSPF uses split-horizon? It
doesn't. If this was a OEQ, then it's a trick question in my opinion.
