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

Tuesday, 18 October 2016

I looked over you scenario in your blog and it is close. I have a single
external port that shares the native VLAN and VLAN27. In my case, I
configrued the external bridge (br-ex) with the native vlan and am now
faced with adding vlan27 to the bridge. RHOSP has a vlan scenario which I
used in creating the bridge and vlans under it that carry the storage, etc.
It would seem that all I need to do is create a vlan27 port as shown below.
The below was generated by the heat OOO heat templates.

 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.
