       Larry, yeah just standard EIGRP hub and spoke on physical with
   IARP mappings between hub and spokes and static maps bewteen spokes.
   Had loopbacks on the spokes to represent attached networks. The loop
   backs on each spoke would show on the hub, but wouldn't show on the
   opposite spoke until I did a "no ip split-horizon eigrp 1" command on
   the hub S0.

     what was the scenario?
     FR Maps? do you have a partial config? Just std EIGRP between a hub
     and two spokes on a single physical interface with 2 frame map
     statements? I want to throw it up in the lab to see, but I would
     like it to be close to what you had.

          Yes, exactly. In fact I was double checking the Caslow book
     before i sent the mail. My hub is 11.1, one of the spokes is 11.3,
     and the other spoke is 12.1. At first I thought it might be just
     the 12.1 code, but it happens int the 11.3 spoke as well.

      In other words, it works like it is supposed to after you enter
     the command no split which should be default for that config?
     
     According to Caslow,
     SH is DIS on FR physical interfaces
     SH is EN on FR point-2-point IP subints
     SH is EN on FR multipt. subints
     
     Unless it is a bug in yur particular IOS ver.
     I will try it tomorrow night with both 12.0 and 11.1

         I have a hub and spoke config with FR, and am running EIGRP.
     The hub will not pass spoke routes to other spokes unless I have
     split horizon disabled on the hub serial int. I am using all
     physical interfaces. By default, split horizon should be already
     disabled on a FR physical int. Anyone else run into this?
