Description David Hill 2018-10-28 15:02:56 UTC 
Description of problem:
In the context of a live datacenter, sometimes the network teams re-organize their VLANs by changing VLAN IDs .  This is pretty straightforward in the context of network configuration and physical servers but when using ML2 VLAN provider networks, those IDs cannot be updated .  The only possible solution here would be to delete those networks and recreate them with a different VLAN ID which might be a problem when you have 1000 VMs and 2000 ports.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Create a VLAN ML2 provider network
2. Try updating the segmentation_id
3.

Actual results:
Fails

Expected results:
Succeeds

All patches related to this feature are merged.

Currently there is support for OVS ML2 mech driver.

This feature is available in Train (OSP16). This feature won't be cherry-picked to previous versions.
