This patch refactors the VPP sphinx docs in order to make it easier to consume for external readers as well as VPP developers. It also makes sphinx the single source of documentation, which simplifies maintenance and operation. Most important updates are: - reformat the existing documentation as rst - split RELEASE.md and move it into separate rst files - remove section 'events' - remove section 'archive' - remove section 'related projects' - remove section 'feature by release' - remove section 'Various links' - make (Configuration reference, CLI docs, developer docs) top level items in the list - move 'Use Cases' as part of 'About VPP' - move 'Troubleshooting' as part of 'Getting Started' - move test framework docs into 'Developer Documentation' - add a 'Contributing' section for gerrit, docs and other contributer related infos - deprecate doxygen and test-docs targets - redirect the "make doxygen" target to "make docs" Type: refactor Change-Id: I552a5645d5b7964d547f99b1336e2ac24e7c209f Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com> Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

Bridge the Interfaces
|
|
---------------------
|
|
|
|
To connect the 2 interfaces we put them on an L2 bridge.
|
|
|
|
Use the "set interface l2 bridge" command.
|
|
|
|
.. code-block:: console
|
|
|
|
vpp# set interface l2 bridge VirtualEthernet0/0/0 100
|
|
vpp# set interface l2 bridge TenGigabitEthernet86/0/0 100
|
|
vpp# show bridge

Bring the Interfaces Up
|
|
-----------------------
|
|
|
|
We can now bring all the pertinent interfaces up. We can then we will then be able to communicate
|
|
with the VM from the remote system running Linux.
|
|
|
|
Bring the interfaces up with :ref:`setintstate` command.
|
|
|
|
.. code-block:: console
|
|
|
|
vpp# set interface state VirtualEthernet0/0/0 up
|
|
vpp# set interface state TenGigabitEthernet86/0/0 up
|
|
vpp# sh int

|

|

|
|
|
|
Ping from the VM
|
|
----------------
|
|
|
|
The remote Linux system has an ip address of "10.0.0.2" we can now reach it from the VM.
|
|
|
|
Use the "virsh console" command to attach to the VM. "ctrl-D" to exit.
|
|
|
|
.. code-block:: console
|
|
|
|
$ virsh console iperf-server3
|
|

On VPP you can now see the packet counts increasing. The packets from the VM are seen as **rx packets**
|
|
on **VirtualEthernet0/0/0**, they are then bridged to **TenGigabitEthernet86/0/0** and are seen leaving the
|
|
system as **tx packets**. The reverse is true on the way in.
