Title:
VLAN Transparency and MTU advertisement coexistence problem
Status in OpenStack Neutron (virtual network service):
Fix Released
Status in neutron kilo series:
Fix Released
Bug description:
Recently added features VLAN Transparency and MTU advertisement can't
be stacked together. When attempting to stack them together the
following traceback shows in the log.
Test Bed:
- Kilo based
- LinuxBridge with VxLAN
- Mutli node - node1: controller/compute, node2: compute, node3: compute.
I can stack and use each of these features individually just not
together.
