OpenDaylight Integration with OpenStack Neutron: A Tutorial

  1. 1. Using OpenStack With OpenDaylight Kyle Mestery, Cisco Ryan Moats, IBM Brent Salisbury, Red Hat Madhu Venugopal, Red Hat 2-5-2014
  2. 2. What You Will Walk Away With • Hands on experience bringing up OpenDaylight on Fedora • Hands on experience bringing up a multi-node OpenStack environment • Hands on experience using OpenDaylight with OpenStack Neutron for virtual tenant networks
  3. 3. Neutron Controller ML2 Plug-In OpenDaylight NorthBound API Layer - -REST APIs OpenDaylight NorthBound API Layer REST APIs OpenDaylight Neutron REST-API OpenDaylight Neutron REST-API OVSDB Neutron Application OVSDB Neutron Application API Driven SAL (ADSAL) API Driven SAL (ADSAL) Configuration Service Inventory Service Connection Service Model Driven SAL (MDSAL) Model Driven SAL (MDSAL) Flow Programmer Connection Service Inventory Service OpenFlow 1.3 SB Plugin OpenFlow 1.0 SB Plugin OVSDB South-bound Plugin OVSDB Protocol Library OpenFlow 1.0 Plugin Netty.io OpenFlow 1.3 Plugin OpenFlow 1.0 Library Bidirectional JSON-RPC Library OpenFlow 1.3 Library Netty io java.nio.socket OVSD B Proto col OpenFlow 1.0 OpenVSwitch Flow Programmer e Op 1.3 low nF
  4. 4. What You Will Need • OpenDaylight Virtualization Edition with OVSDB • Can be in a VM or on your laptop directly • Two or more OpenStack Nodes • One node running control software and optionally compute services • One or more compute nodes
  5. 5. Logistics • The Fedora20 VM has the following information: • Users: • root/password • odl/odl • Setup for DHCP for the image itself.
  6. 6. Boot Your VM Images • Boot the VM which you will run OpenDaylight inside of. • Optionally bring-up OpenDaylight on your laptop natively. • This will work in either scenario. • Verify IP addresses on your VMs (may require reboots). • This should be done for all VMs. • This may change once you import the OVF file.
  7. 7. OpenDaylight Configuration and Startup • Edit your ODL configuration: • opendaylight/configuration/config.ini (change of.address) • Optionally enable OpenFlow 1.3 • opendaylight/configuration/config.ini (uncomment this) • Bring OpenDaylight to life: • Handy RUN.sh script • This contains options for both OpenFlow 1.0 (default) or OpenFlow 1.3 (optional) • Post ODL fixup: • From OSGI console: • lb | grep simple • stop <simple forwarding ID>
  8. 8. OpenStack VM Setup • Copy the VM image twice: • Once for control and once for compute • On both nodes: • cd /etc/sysconfig/networking-scripts • sudo cp ifcfg-eth0 ifcfg-eth1 • Edit ifcfg-eth1 to change interface name • On the control node: • Login as odl/odl • Copy local.conf.control to devstack/local.conf • Edit devstack/local.conf and change IP addresses • On the compute node: • Login as odl/odl • Copy local.conf.compute to devstack/local.conf • Edit devstack/local.conf and change IP addresses
  9. 9. Example of stopping Simple Forwarding
  10. 10. Browse to your ODL Window over HTTP
  11. 11. Boot Up Your OpenStack Instances • Control Node: • cd devstack • ./stack.sh • Compute Node: • cd devstack • ./stack.sh
  12. 12. Your devstack will look like this
  13. 13. Login to Horizon (go to the IP of your control node)
  14. 14. Login as (admin/ad min) to see the Horizon Dashboard
  15. 15. Spinup a VM
  16. 16. Spinup a VM (cont.)
  17. 17. Instance is now booted
  18. 18. Repeat process for a second VM
  19. 19. Checkout OpenDaylight Web GUI
  20. 20. Ping test between VMs
  21. 21. Thank You!
