David,
Split Horizon is turned off by default because in a partial mesh hub & spoke
topology, spoke routers running distance vector routing protocol (EIGRP/RIP)
will not be able to send routing update to other spoke routers. That is if
you are not running point-to-point subinterfaces
This is because routing updates enter and exits through the same physical
interface, even though they are separate PVCs, Split Horizon stops the
update for this reason along.
I don't think Split Horizon gets disabled by default if you use
point-to-point subinterfaces. Look at Caslow's explanation for more details.
Hope this helps.
Vincent Tsang
