How can I configure my RHEL 6 or 7 High Availability cluster with pacemaker to monitor the link status of a network interface and relocate resources if a failure occurs?

Issue

I am running an IPaddr2 resource in my cluster, but it doesn't react when the link goes down. How can I tell pacemaker to monitor the link and run this resource on a node that has an active link?
I'm using the ethmonitor resource agent and it logs monitor failures when the link goes down, but the resource doesn't fail or move to another location.
How can I configure my cluster to monitor a network link and move resources somewhere else if the link fails?

Environment

Red Hat Enterprise Linux (RHEL) 6 or 7 with the High Availability Add On
pacemaker
One or more network interfaces that need to be monitored for health
