Hi,

You first need to make sure that disabling split horizon is not going to
introduce a routing loop. That depends on the frame relay logical topology.
If it is pure hub-and-spoke, then it is safe to disable split horizon in the
hub interface.

By default, in FR multipoint/physical interfaces, split horizon is:

Disbled for RIP.
Enabled for EIGRP.
 
Another situation where you may want to disable split horizon is for
interfaces with secondary IP addresses.

Cheers,
Ato.

Is there a specification for each routing protocol as to when you must
enab;e/disable split horizon on an interface. For instance, between two
physical frame relay interface, and running eigrp, must split horizon be
disabled on one end?
