# A Heat environment file that enables DVR in the overcloud.
# This works by configuring L3 and Metadata agents on the
# compute nodes.
resource_registry:
OS::TripleO::Services::ComputeNeutronL3Agent: ../puppet/services/neutron-l3-compute-dvr.yaml
OS::TripleO::Services::ComputeNeutronMetadataAgent: ../puppet/services/neutron-metadata.yaml
# With DVR enabled, the Compute nodes also need the br-ex bridge to be
# connected to a physical network.
OS::TripleO::Compute::Net::SoftwareConfig: ../net-config-bridge.yaml
parameter_defaults:
# DVR requires that the L2 population feature is enabled
NeutronMechanismDrivers: ['openvswitch', 'l2population']
NeutronEnableL2Pop: 'True'
# Setting NeutronEnableDVR enables distributed routing support in the
# ML2 plugin and agents that support this feature
NeutronEnableDVR: true
# We also need to set the proper agent mode for the L3 agent. This will only
# affect the agent on the controller node.
