Connecting Two FD.io VPP Instances
|
|
==================================
|
|
|
|
.. _background-1:
|
|
|
|
memif is a very high performance, direct memory interface type which can
|
|
be used between FD.io VPP instances. It uses a file socket for a control channel
|
|
to set up shared memory.

Skills to be Learned
|
|
---------------------
|
|
|
|
You will learn the following new skill in this exercise:
|
|
|
|
#. Create a memif interface between two FD.io VPP instances
|
|
|
|
You should be able to perform this exercise with the following skills
|
|
learned in previous exercises:
|
|
|
|
#. Run a second FD.io VPP instance
|
|
#. Add an ip address to a FD.io VPP interface
|
|
#. Ping from FD.io VPP

Running a second FD.io VPP instances
|
|
-------------------------------------
|
|
|
|
You should already have a FD.io VPP instance running named: vpp1.
|
|
|
|
Run a second FD.io VPP instance named: vpp2.
|
|
|
|
.. code-block:: console
|
|
|
|
$ sudo /usr/bin/vpp -c startup2.conf
|
|
....

$ sudo vppctl -s /run/vpp/cli-vpp2.sock

|
Create memif interface on vpp1
|
|
-------------------------------
|
|
|
|
Create a memif interface on vpp1. To connect to the instance vpp1 use the
|
|
socket **/run/vpp/cli-vpp1.sock**
|
|
|
|
.. code-block:: console
|
|
|
|
$ sudo vppctl -s /run/vpp/cli-vpp1.sock
|
|
vpp# create interface memif id 0 master
|
|
|
|
This will create an interface on vpp1 memif0/0 using /run/vpp/memif as
|
|
its socket file. The role of vpp1 for this memif inteface is 'master'.
|
|
|
|
With what you have learned:
|
|
|
|
#. Set the memif0/0 state to up.
|
|
#. Assign IP address 10.10.2.1/24 to memif0/0
|
|
#. Examine memif0/0 via show commands
|
|
|
|
.. _action-create-memif-interface-on-vpp2-1:
|
|
|
|
Create memif interface on vpp2
|
|
--------------------------------
|
|
|
|
We want vpp2 to pick up the 'slave' role using the same
|
|
run/vpp/memif-vpp1vpp2 socket file
|
|
|
|
.. code-block:: console
|
|
|
|
vpp# create interface memif id 0 slave
|
|
|
|
This will create an interface on vpp2 memif0/0 using /run/vpp/memif as
|
|
its socket file. The role of vpp1 for this memif inteface is 'slave'.
|
|
|
|
Use your previously used skills to:
|
|
|
|
#. Set the memif0/0 state to up.
|
|
#. Assign IP address 10.10.2.2/24 to memif0/0
|
|
#. Examine memif0/0 via show commands
|
|
|
|
.. _action-ping-from-vpp1-to-vpp2-1:
|
|
|
|
Ping from vpp1 to vpp2
|
|
------------------------
|
|
|
|
Ping 10.10.2.2 from vpp1
|
|
|
|
.. code-block:: console
|
|
|
|
$ ping 10.10.2.2
|
|
|
|
Ping 10.10.2.1 from vpp2
|
|
|
|
.. code-block:: console
|
|
|
|
$ ping 10.10.2.1
