Convention for heading levels in Neutron devref:
|
|
======= Heading 0 (reserved for the title in a document)
|
|
------- Heading 1
|
|
~~~~~~~ Heading 2
|
|
+++++++ Heading 3
|
|
''''''' Heading 4
|
|
(Avoid deeper levels because they do not render well.)

L2 Networking with Linux Bridge
|
|
===============================
|
|
|
|
This Agent uses the `Linux Bridge
|
|
<http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge>`_ to
|
|
provide L2 connectivity for VM instances running on the compute node to the
|
|
public network. A graphical illustration of the deployment can be found in
|
|
`Networking Guide
|
|
<http://docs.openstack.org/networking-guide/scenario_legacy_lb.html>`_
|
|
|
|
In most common deployments, there is a compute and a network node. On both the
|
|
compute and the network node, the Linux Bridge Agent will manage virtual
|
|
switches, connectivity among them, and interaction via virtual ports with other
|
|
network components such as namespaces and underlying interfaces. Additionally,
|
|
on the compute node, the Linux Bridge Agent will manage security groups.
|
|
|
|
Three use cases and their packet flow are documented as follows:

2. `High Availability using L3HA with Linux Bridge
