<title>High availability</title>
<para>The use of high availability in a Networking deployment
helps mitigate the impact of individual node failures. In general, you
can run <systemitem class="service"
>neutron-server</systemitem> and <systemitem
class="service">neutron-dhcp-agent</systemitem> in an
<glossterm baseform="active/active configuration">active/active</glossterm>
fashion.
You can run the <systemitem
class="service">neutron-l3-agent</systemitem> service
as <glossterm baseform="active/passive configuration">active/passive</glossterm>,
which avoids IP
conflicts with respect
to gateway IP addresses.</para>

<title>Networking high availability with Pacemaker</title>
<para>You can run some Networking services in a cluster
configuration (active/passive or active/active for
Networking server only) with Pacemaker.</para>
