Doesn't that make the stack very inflexible? And yes, we have faced this issue before and talked to RH about it and they said exactly the same thing. However, if I redeploy, I have found that modifying the network config does not take affect and I have to delete and redeploy the overcloud. That would really reak havoc if I had to do that in production.Thanks for the reply.On Tue, Oct 18, 2016 at 8:43 AM, Boris Derzhavets <bderzhavets@hotmail.com> wrote:Sorry for typo

I skipped "if" on first place.

Subject: Re: [rdo-list] Adding a vlan to the external network in tripleoI have a lab situation where there are 2 networks. One is in one DMZ and the other is a lab isolated network. I need access to both via the external port. I believe what I need to do is add another port to the bridge on a vlan to the lab network. I created a new external network in Director and assigned the vlan to it. However, I am not sure that will add it to the existing bridge.
A bigger question around this is why does Openstack not support modifications after installation to the north/south network?
Openstack has no problem with adding one more external network (or even 2) of VLAN type .
See for instance https://www.linux.com/blog/rdo-mitaka-several-external-netwo rks-vlan-provider-setup
The problem here is the way which was used for deployment, it is TripleO.
To have the job done you need to update heat stack "overcloud" which had been built
on undercloud Node. So you should be able redeploy overcloud with specific tripleo-heat-template
addressing you needs. I would expect your br-ex bridges to have IPs on ctlplane obtained via DHCP.
Any manual intervention to overcloud is impossible. You have presumably only one
option , which is to ask vendor for support.
I am not correct stating the above, RH's technical stuff will point to my mistake for sure.
That is why I am so sorry about regression taken place in packstack functionality
Boris.
East/west is easy but North/South has to have a lot of modifications made to static files (it seems) like plugin.ini and openvswitch.ini.

Any help would be appreciated.
