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.
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
Apparently the CLI defaults this too...
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.
