NOTE: This page is under construction.

This example shows how to configure and run sample client/server applications using user mode mTCP in 2 linux namespaces (or containers) which communicate through VPP via netmap virtual interfaces.

In this setup we use 2 different namespaces called vpp1 and vpp2 and two sample applications epserver and epwget available with mTCP.

Setup

NETMAP

Download the sources from the upstream repository using following command:

  git clone git@github.com:vpp-dev/netmap.git

OR

  https://github.com/vpp-dev/netmap/archive/master.zip

Enter LINUX directory and configure netmap. To compile only NETMAP/VALE (using unmodified drivers):

./configure --no-drivers

make

make apps

sudo insmod netmap.ko

lsmod | grep netmap

VPP



mTCP

Download the sources using following command:

  git clone git@github.com:vpp-dev/mtcp.git

OR

  https://github.com/vpp-dev/mtcp/archive/master.zip
./configure --enable-netmap

goto tcp/src/

make

goto apps/example

make

Configure Interfaces

VPP

Run VPP/VPP-lite and create netmap interfaces using following commands:

        create netmap name vale00:vpp1 hw-addr 02:FE:3F:34:15:9B pipe master
        create netmap name vale00:vpp2 hw-addr 02:FE:75:C5:43:66 pipe master

        set int state netmap-vale00:vpp2 up
        set int state netmap-vale00:vpp1 up

        set int l2 xcon netmap-vale00:vpp1 netmap-vale00:vpp2
        set int l2 xcon netmap-vale00:vpp2 netmap-vale00:vpp1

Modify Config Files


Test


Using the VPP debug Command-line Interface (CLI) we can verify interface statistics.

Use the VPP CLI command :


Use the command show interface:



Use the command :
