 Download the VPP code:

     git clone https://gerrit.fd.io/r/vpp --branch stable/1704
     cd vpp
     git reset --hard e3b7ad7adebf25af1651a217da8534ada89c369b
 
 Patch the code before compiling:
+
     cp <oor_dir>/VPP/vpp.patch .
     git apply vpp.patch
 
 Install dependecies:
+
     sudo make install-dep
     sudo apt-get install python-cffi python-ply python-pycparser
 
 Finally, we compile and install VPP:
+
     cd build-root
     ./bootstrap.sh
     make V=0 PLATFORM=vpp TAG=vpp install-deb
     sudo dpkg -i *.deb

    sudo ifconfig eth1 down

 == Notice that the current version of VPP is only a traffic forwarder. Don't assign 
 to VPP the management interface of the PC. ==
 
 Start VPP:
+
     sudo service vpp start
 
 List the interfaces assigned to VPP:
+
     vppctl show interface
 
 Configure VPP interfaces:
 
 Assign an address to the interface:
+
     sudo vppctl set int ip address [del] <iface name> <ip address/mask>
 
 Set status of the interface to up:
+
     sudo vppctl set int state <iface name> up|down
 
 Show the interfaces addresses:
+
     vppctl show int addr
 
 If you want to use IID different to 0 (only works with local networks), you will have 
 to do a previous step before configuring the interface associated with the EIDs:
+
     sudo vppctl set interface ip|ip6 table <iface_name> <iid>
 
 Once you have configured vpp you can start to use OOR.
