Installing the scripts.
Installing these scripts (along with the documentation) should be straight forward:
download the archive: wget http://www.elcom.pub.ro/~adrian.popa/mpls-linux/mpls-linux-labs_v1.950.tar
cp mpls-linux-labs_v1.950.tar /tmp
tar xvf mpls-linux-labs_v1.950.tar
cp -ar mpls-linux-labs_v1.950/computer_name/scripts.tar /root
tar xvf scripts.tar
Note: The experiments were developed for mpls-linux version 1.950, so they might not work for other versions of mpls-linux! If somebody ports some/all experiments to newer versions, please release the updated scripts.
Note2: In the commands above, computer_name is the name of this computer (for example E1, A2, etc. This is because all the scripts on all the computers are bundled in the same archive, but you only need one directory per computer.
Note3: From now on, your current working directory is assumed to be /root/mpls-linux-labs_v1.950/computer_name/ and all commands are relative to this path. Again, computer_name varies from computer to computer.
Note4: In addition to these scripts, you'll also need to download 4 movie clips and save them on A3 and A1 in /home/username/media. You'll also need to modify the video-server.sh script (in the experiments that use it) to point to your media directory. Please note that these movie clips are optional, and you can build your own movie clips from a TV tuner or an avi file, but please keep in mind that all movie clips have a data rate of 4000kbps! If you wish to download these clips, be warned that they are about 256MB in length!
Clip A (46MB): “Discovery Channel”, 90s, 320x240, 30fps, 4000kbps, used in “QoS-based TE”, “Link protection”, “E-LSP”, “L-LSP” - http://www.elcom.pub.ro/~adrian.popa/mpls-linux/media/a.mpg
Clip B (30MB): “National Geographic”, 60s, 320x240, 30fps, 4000kbps, used in “QoS-based TE” - http://www.elcom.pub.ro/~adrian.popa/mpls-linux/media/b.mpg
Clip C (30MB): “Animal Planet”, 60s, 320x240, 30fps, 4000kbps, used in “E-LSP”, “L-LSP” - http://www.elcom.pub.ro/~adrian.popa/mpls-linux/media/c.mpg
Clip F (151MB): “National Geographic – 2”, 6m, 320x240, 30fps, 4000kbps, used in “Node protection” - http://www.elcom.pub.ro/~adrian.popa/mpls-linux/media/f.mpg

Here is a series of steps you need to complete to install mpls-linux on all the 'core' computers (E1-E5). The installation was done in Debian Linux, but the steps are similar for other distributions. The installation uses mpls-linux version 1.950; for the current and newer versions, please read the readme in the mpls-linux project page first.
Download the necessary packets from the net. These include Kernel 220.127.116.11, mpls-linux and iptables, iproute, ebtables with MPLS support.

Untar the Linux kernel and mpls-linux package. Apply the patch to the kernel to add MPLS support. When applying the pacth, it's very important that the user receives the italic output.

configuring the kernel. The user will activate all modules and
drivers needed for the correct functioning of his system. In
addition MPLS support will be added. These additional elements must
be added so that they can be used by the scripts.
BEWARE: A wrong kernel configuration CAN result in an unbootable system!!!

Ok. you're ready. Make sure the kernel compiled correctly and restart your computer(s). On reboot, select the MPLS kernel and you're good to go. To verify that there is MPLS support in the new kernel, after reboot run dmesg |grep MPLS and you should get some output.
Note: If you chose to install things as modules, MAKE SURE that they load before running the scripts, or you could get errors!
