<div><br>
</div>
<div>1. When a new Neutron network is created, it is
automatically scheduled to one of DHCP-agents running in a
cluster (actually, it's done lazily, when the first port on
this network is created, but that's an implementation detail).
Though, you have to manually schedule it to additional
DHCP-agents to provide HA. I haven't seen any BPs adding such
an option, but I agree, that it would be useful to have one.</div>

It already exists in Havana by setting the dhcp_agents_per_network
parameter in neutron.conf

<div>2. Not sure we have one :( The solution from TelekomCloud
guys seems to be the only way to go to provide HA for L3
agents in Active/Active mode currently. </div>

</div>
<div>3. Every network or compute node in a cluster runs an
L2-agent, which allows one to create L2 tenant networks and
plug VMs/routers/DHCP-servers into network ports (the
underlying implementation depends on the core plugin you use,
e.g. OVS can use VLANs or GRE tunnels to provide tenant
isolation). So L2 networking is ready to use when you've
started an L2-agent and provided it with a correct
configuration file.</div>
