Misread your question: On a multipoint Frame interface, spoke to spoke route
propagation will be achieved by disabling split horizon for IGRP,EIGRP,and
RIP1+2. OSPF will not have an issue. I don't think BGP will have an issue
either.

Subject: Split Horizon
Looking for help with clarification on Split Horizon when using point to
multipoint on sub interfaces...
It is my understanding that when you enable frame relay on a "Physical"
interface, it automatically disables split horizon. So when running the
below protocols, when do I need to make sure that split horizon is running
vs
not running on sub interfaces in a point to multipoint enviornment.
RIP 1&2 ( I believe I want split horizon shut off)
EIGRP Off??
IGRP Off??
OSPF Off??
BGP off??
In its most basic form I thought that In a point-to-multipoint enviornment I
want it off all the time in order for routing updates to be sent back out
the
same physical interface it was learned on. This leads me to think I need
it
off all the time. The various labs I have looked at don't seem to be
consistant so I am in a quandry.
Any help on this one out there??
