You're right. That's not a good idea.
We don't have a default route resource agent. You could take the
command you added to IPaddr2, and then write your own resource agent
around this command.
If you want it to be an OCF resource agent (which I would suggest), then
you need to write these actions:
start save old route and set new one
stop restore old default route
monitor see if route is still there
metadata return information about this resource agent
The following are optional:
verify-all tell if parameters are all present and legal
status (status is required for LSB compliance)
can be the same action as monitor.
Return codes for error cases technically should
be slightly different.
Hope this helps.
