[rdo-list] Adding a vlan to the external network in tripleo

[Boris Derzhavets]

Sorry for typo

  If I am not correct stating the above, RH's  technical stuff will point to my mistake for sure

I skipped "if" on first place.

I 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-networks-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.
