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-1:
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

Initial state
--------------
The initial state here is presumed to be the final state from the
exercise `Create an
Interface <VPP/Progressive_VPP_Tutorial#Exercise:_Create_an_Interface>`__
.. _action-running-a-second-vpp-instances-1:
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

.. _action-create-memif-interface-on-vpp1-1:
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 interface 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 interface 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
