Run Networking L3 agent

Run Networking L3 agent

The Networking (neutron) service L3 agent is scalable, due to the scheduler that supports Virtual Router Redundancy Protocol (VRRP) to distribute virtual routers across multiple nodes.

To enable high availability for configured routers, edit the /etc/neutron/neutron.conf file to set the following values:

/etc/neutron/neutron.conf parameters for high availability
Parameter Value Description
l3_ha True All routers are highly available by default.
allow_automatic_l3agent_failover True Set automatic L3 agent failover for routers
max_l3_agents_per_router 2 or more Maximum number of network nodes to use for the HA router.
min_l3_agents_per_router 2 or more Minimum number of network nodes to use for the HA router. A new router can be created only if this number of network nodes are available.
