Bruce, your suggestion worked like a magic.

Not to sound stupid, but shouldn't the ipx traffic follow the route back
to the hub, then the hub route the traffic to the other spoke?

I understand why the fix works, because then anything looking for that
explicit ipx address, in my case 111.0004.0004.0004 and
111.0005.0005.0005 rides the dlci to the hub, then the hub transmits the
traffic on the other dlci. But of course each spoke already had a route
for 111 to the hub.

This must be a ipx issue, ip and/or arp doesn't do this.

Thanks, Michael

I just learned something I never thought about.

Below is my uncorrected configs, I was getting ready to send before I
got your email.
