    Okay, I cleared the config, retyped it, and rebooted. The spoke routes
are not showing. Here's the "sho ip int S0" output. It look like for EIGRP,
split horizon is NOT disable on physcial FR interfaces, even though the
output of this command says different.
    As sonna s I go in and add "no ip SH etc., etc.,", the spoke route shows
up in the other spoke. I've done it about 50 times now!

    r1#sho ip int s0
Serial0 is up, line protocol is up
  Internet address is 10.1.1.1/24
  Broadcast address is 255.255.255.255
  Address determined by non-volatile memory
  MTU is 1500 bytes
  Helper address is not set
  Directed broadcast forwarding is enabled
  Multicast reserved groups joined: 224.0.0.10
  Outgoing access list is not set
  Inbound access list is not set
  Proxy ARP is enabled
  Security level is default
  Split horizon is disabled
  ICMP redirects are always sent
  ICMP unreachables are always sent

  IP fast switching is enabled
  IP fast switching on the same interface is enabled
  IP multicast fast switching is disabled
  Router Discovery is disabled
  IP output packet accounting is disabled
