Learning OpenStack Networking (Neutron) - Second Edition

Configuring Neutron

Neutron uses default settings to determine the type of routers that tenants are allowed to create as well as the number of routers that should be deployed across L3 agents.

The following default settings are specified within the Neutron configuration file at /etc/neutron/neutron.conf and only need to be modified on the host running the Neutron API service. In this environment, the neutron-server service runs on the controller node:

# =========== items for l3 extension ==============
# Enable high availability for virtual routers.
# l3_ha = False
#
# Maximum number of l3 agents which a HA router will be 
# scheduled on. If it is set to 0 the router will be scheduled on
# every agent.
# max_l3_agents_per_router = 3 # # Minimum number ...
