Description of problem:
In RDO, the default network type is GRE. We should change this to VXLAN for several reasons: VXLAN has better performance (20-25% better); NICs with VXLAN offload are more common.
Steps to Reproduce:
Deploy overcloud with RDO without specifying a network type
GRE is the default
VXLAN should be the default
This is due to python-tripleoclient not having this patch:
It's overriding the default in tripleo-heat-templates. You can see the default in THT in /usr/share/openstack-tripleo-heat-templates/puppet/controller.yaml
This bug was accidentally moved from POST to MODIFIED via an error in automation, please see firstname.lastname@example.org with any questions
vxlan is now the default so this can be closed.
