[Pacemaker] IPaddr2 monitoring failure

I have a few clusters that we are about to put into production.
One of the tests was to pull the public network cable on the
node that hosted the Virtual IP for the Cluster.
We did and the Virtual IP didn't move. It stayed on the node originally
selected.
Now, I'm thinking that I don't have the configuation setup correctly.
Setup: 3 to 5 nodes. Two Private switches for corosync/pacemaker
communications.
Active-Backup Bond into the private switches.
Public Interfaces of all the nodes on the same network and pingable between
them.
corosync 1.4.2.
openais 1.1.3
pacemaker 1.1.5
cluster-glue 1.0.6
resource-agents 1.0.4
RHEL5 with 2.6.32.49 kernel.

Should IPaddr2 correctly detect link loss and move the Virtual IP?
Examining the code doesn't show that it would detect that failure.
What other resources/agents would recommend be configure to correctly
migrate
the Virtual IP?
