Comment 2 for bug 1439696

After unstacking and re-stacking, when the heat template is run for the first time, does it start the neutron lbaas agent ?

I have seen the 404 error (The resource could not be found) for "neutron lb-healthmonitor-create" when the neutron lbaas agent is not running.

Refer https://wiki.openstack.org/wiki/Neutron/LBaaS/HowToRun to setup and run the lbaas agent. Ideally, the heat template should do this.

I can run the commands successfully when the neutron lbaas agent is running.
