OpenVSwitch L2 Agent
|
|
====================
|
|
|
|
This Agent uses the `OpenVSwitch`_ virtual switch to create L2
|
|
connectivity for instances, along with bridges created in conjunction
|
|
with OpenStack Nova for filtering.
|
|
|
|
ovs-neutron-agent can be configured to use two different networking technologies to create tenant isolation, either GRE tunnels or VLAN tags.
|
|
|
|
