Description Dan Sneddon 2015-07-20 11:53:10 EDT

Description of problem:
In OSP-director, 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; OSP 5/6 had VXLAN as a recommended tunnel type.

Version-Release number of selected component (if applicable):
puddle-2015-07-17

How reproducible:
100%

Steps to Reproduce:
1. Deploy OSP 7 without specifying a network type
2.
3.

Actual results:
GRE is the default

Expected results:
VXLAN should be the default

Additional info:
I was discussing this with Assaf Muller in the Neutron team, and Hugh Brock. We all agree that VXLAN is a more sane default.

Comment 6 Alexander Chuzhoy 2015-09-17 12:44:06 EDT

FailedQA

Environment:
openstack-tripleo-heat-templates-0.8.6-62.el7ost.noarch

grep ^tenant_network_types /etc/neutron/plugins/ml2/ml2_conf.ini
tenant_network_types = gre

Comment 7 Mike Burns 2015-09-17 14:43:50 EDT

Apparently the CLI defaults this too...

Comment 9 Alexander Chuzhoy 2015-09-18 15:27:23 EDT

Verified:


Environment:
python-rdomanager-oscplugin-0.0.10-4.el7ost.noarch

grep ^tenant_network_types /etc/neutron/plugins/ml2/ml2_conf.ini
tenant_network_types = vxlan


Also launched an instance attached to the network, created with "--provider:network_type vxlan" and verified connectivity.
