3 node active-active-passive setup

Salaam,

I did some experimentation with wackamole and set up an =

active-active-passive cluster, say node A, node B and node C

I have assigned the following vip
192.168.0.1 to Node A
192.168.0.2 Node B

Node C is configured to take over any node that fails, The following is my =
conf file

For Node A
{code}
Spread =3D 4803
SpreadRetryInterval =3D 5s
Group =3D wack1
Control =3D /var/run/wackamole/wackamole.it

Prefer eth0:192.168.0.1/32

VirtualInterfaces {
=A0 =A0 =A0 =A0 eth0:192.168.0.1/32
}

Arp-Cache =3D 60s
balance {
=A0 =A0 =A0 =A0 AcquisitionsPerRound =3D all
=A0 =A0 =A0 =A0 interval =3D 4s
}
mature =3D 5s
{code}

For Node B the conf file is
{code}
Spread =3D 4803
SpreadRetryInterval =3D 5s
Group =3D wack1
Control =3D /var/run/wackamole/wackamole.it

Prefer eth0:192.168.0.2/32

VirtualInterfaces {
=A0 =A0 =A0 =A0 eth0:192.168.0.2/32
}

Arp-Cache =3D 60s
balance {
=A0 =A0 =A0 =A0 AcquisitionsPerRound =3D all
=A0 =A0 =A0 =A0 interval =3D 4s
}
mature =3D 5s
{code}

The conf file for the Node c ie the passive node is
{code}
Spread =3D 4803
SpreadRetryInterval =3D 5s
Group =3D wack1
Control =3D /var/run/wackamole/wackamole.it

Prefer None

VirtualInterfaces {
=A0 =A0 =A0 =A0 eth0:192.168.0.1/32
=A0 =A0 =A0 =A0 eth0:192.168.0.2/32
}


Arp-Cache =3D 60s
balance {
=A0 =A0 =A0 =A0 AcquisitionsPerRound =3D all
=A0 =A0 =A0 =A0 interval =3D 4s
}
mature =3D 5s
{code}

I have used prefer for Node A and Node B so that the Node C releases the VI=
P once the original node comes online

I tested this setup internally and it works just fine.

But when I tried to implement this in the live environment, problems starte=
d and the setup started behaving strangly, once the Node C takes up the ip =
from the Node A and B, it just never gives them back even after mentioning =
the Prefer directive

In the live environment the=A0 only difference is that
1) it is sub netted
2) switch has spanning tree enabled =


can someone please point out where I am going wrong ?

Thanks for your time.
