I need some advice on dual homing.  I want to use DH, Dual Homing,
to satisfy a conflict; our users want redundant access to some
servers on the FDDI and, even though the servers have DAS cards,
I don't want them on my main ring.  What I was planing on doing
as a fix was cross couple the stations across two concentrators,
which I understand is called dual homing.   This is a picture of
what I want to do.  Can I just plug these guys in and expect them
to work this way?

Thanks,
