<note>
|
||
<para>The neutron L2 agent does not need to be highly available. It has to be
|
||
installed on each Data Forwarding Node and controls the virtual networking
|
||
drivers as Open vSwitch or Linux Bridge. One L2 agent runs per node
|
||
and controls its virtual interfaces. That’s why it cannot be distributed and
|
||
highly available.</para>
