CORD Fabric - Installation Guide

ONOS

1. Setup an ONOS cluster with 3 instances. Please refer to Installing and Running ONOS for detail.

2. Enable following applications in your cell configuration:

   ONOS_APPS=drivers,openflow,segmentrouting

3. Configure Segment Routing

   We plan to replace this with Network Configuration Subsystem in a near future

Mininet

1. Install Mininet from source code. Please refer to Install Mininet from source code for detail.

   Fetch Mininet

   git clone git://github.com/mininet/mininet
   cd mininet
   git checkout -b 2.2.1 2.2.1

2. Patch Mininet.

   A patch is required to allow CpqD software switches to connect to multiple controller instances simultaneously. We will probably commit this back to the Mininet main stream

   Patch Mininet

3. Install Mininet

CpqD Software Switch

1. Install CpqD

   Install CpqD

   git clone https://github.com/CPqD/ofsoftswitch13.git
   cd ~/ofsoftswitch13
   ./boot.sh
   ./configure
   make
   sudo make install

Start the Fabric

1. Start the Fabric
   We write a Mininet script that can help you easily create a leaf-spine topology with CpqD software switches.
   
   

2. Run pingall

   Communication between hosts in the same rack (i.e. in the same subnet) is L2 bridged (not segment-routed). Unfortunately, we have not implemented this functionality yet. As a result pinging between hosts in the same rack (e.g. h1 and h2) will not work 

(Optional) GUI Configuration 

1. Configure topology view
2. Configure sprites
