Multiple NICs - Configuring Management vs Public Networks

Hi,

Trying to set up a multi node instance of RDO Packstack. According to documentation, there should be a separate nic for management network for communication between nodes, in addition to a nic reserved for compute-neutron

I have the following NICS:

eth0 - Public Network ( eg 10.20.x.x)

eth1 - Management Network (eg. 192.168.x.x)

eth2 - For Compute - Neutron (data for vms)

By default, if I run packstack on a generated answer file, when I look at the endpoints summary in horizon, internalurl, publicurl, and adminurl are all with the same IP that I specified during install (10.20.x.x).

I want to break it out such that publicurl refers to the 10.20.x. IP, and internal/admin use the management network (192.168.x.x)

I can't seem to figure out what to set in the answerfile, or whether this is set post installation?

Thanks!

Have you made required manual updates to generated answe-file or just used as it was ?

Yes, made modifications to answer file to point to the different hosts for each node I'm assuming that at some point during the packstack installation, it is calling the "service create endpoint" or "keystone-manage --bootstrap-admin-url etc" commands. Possible to set these in ans file b4 install?

Have you done anything else ?

No, I haven't modified other vars yet - When looking into the controller.pp.log file, I can see that public_url, admin_url and internal_url are set. I see that this is from service_identity.pp -- however I'm not sure how to feed it the values I want (e.g. 10.20.x and 192.168.x).
