[Linux-cluster] How do I use a cross over cable to set up quorum?

[Andreso]

Hello,

I am trying to set up a cluster with clumanager-1.2.3-1 and
clumanager-1.2.3-1 and my boss desires a working quorum where the two
members of the cluster use a cross over cable to interchange the
necessary information for quorum between the two cluster members.  The
reason is that the company uses faulty switches so he considers using
the main network interfaces of the servers not acceptable.

I would like to know how I can obtain cluster quorum using the cross
over cable.  I have succesfully set up the cluster using the main
network interface but I have failed miserably setting up the cluster
quorum over the cross over cable network interface.  I believe I have
a routing problem.

The route -n information for the cross over cable interface is
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.0.0.0        0.0.0.0         255.255.255.0   U     0      0        0 eth1

I am far from being a linux expert and in some things like clusters I
am a newbie and I am not particularily strong on networking.  For
example until I started setting up the cluster I had never heard of
the concepts tiebreaker IP or Multicast IP address.

Any help would be appreciated.

If somebody has managed to make this work could they please post their
cluster.xml file?
