### Generic Neutron Config
###

# Fatal Deprecations

# If ``neutron_api_workers`` is unset the system will use half the number of available VCPUs to
# compute the number of api workers to use with a default capping value of 16.

neutron_report_interval: "{{ neutron_agent_down_time | int / 2 | int }}"

neutron_external_network_bridge: ""

neutron_dns_domain: "openstacklocal."

# If ``neutron_num_sync_threads`` is unset, the system will use the value of
# neutron_api_threads in templates/dhcp_agent.ini.j2 for num_sync_threads.
# neutron_num_sync_threads: 4

###
### DNSMasq configuration
###
# Disable dnsmasq to resolve DNS via local resolv.conf.

# and neutron_dnsmasq_noresolv is set to True, dnsmasq will reply with
# empty respose on DNS requests.
