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 commands: 

  git clone git@github.com:luigirizzo/netmap.git

OR 

  https://github.com/luigirizzo/netmap/archive/master.zip


Apply the following patch on top of cloned sources: 

  git am 0001-Netmap-Disable-namespaces-for-vale-switch.patch

OR 

  patch -p1 < 0001-Netmap-Disable-namespaces-for-vale-switch.patch

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

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:
