Joe,
IP split-horizon is disabled by default ONLY for physical Frame-Relay
and SMDS interfaces. Subinterfaces do not have IP split-horizon disable
by default.

As soon as you configure the subinterface, split horizon is
automatically
disabled. This is the default behavior. So the only reason that you
see
the "no ip split-horizon" line in the config is because it was added
automatically by the IOS when the subif was created.

hi guys,
simple and short: does split-horizon rule effects OSPF routing update
(LSAs)
propogation or OSPF process generaly? My personal view is it doesnt (due
to
link-state), but I have seen some configs, where the only IGP was OSPF
and
split-horizon was disable on all frame-relay subinterfaces.

Azhar M.
