Hi
I have two machines where in I simulated Multi node setup (2 compute nodes + 1 openstack controller + 1 Opendaylight)
Integrated stable kilo devstack and latest release of ODL Lithium SR1 to use ODL as neutron backend and L3 forwarder.
1. Able to create networks (net1 and net2)
2. Able to launch VM's on the compute Nodes (VM1 in CN1 attached to net1 && VM2 in CN2 attached to net2)
3. Not able to ping between VM's, VM1 and VM2
- GRE is the network type
- Enabled L3 forwarding in ODL - etc/custom.properties
- Some more attributes are added in Openstack controller to inform it that we are using L3 from ODL
local.conf files can be downloaded from here
compute Node local.conf :
http://fpaste.org/263578/44136961/
password 12345
Controller Node local.conf :
http://fpaste.org/263580/44136973/
password 12345
I am following the links :
http://www.flaviof.com/blog/work/how-to-odl-with-openstack-part2.html
http://www.flaviof.com/blog/work/how-to-odl-with-openstack-part1.html
As told in the link, when the gre tunnel is created, flows are populated in table 0 and table 110 across all the nodes and when the router is created and network interfaces are attached to it from Horizon UI
table 60 and 70 are not populated with L3 entries.

Hi, I could see a Null pointer exception while programming tunnel rules and it is related to L2. In your case the missing flows are related to DVR and L3_forwarding. Please restart the setup (run ./unstack.sh and ./clean.sh) and bring-up from scratch. I have attached my sample conf files, which I have used for testing Vxlan (Cross verify them with yours). I could see many PORT DELETE southbound and OVSDB Disconnect messages. Did you delete any network/port/ovsdbconnection? I hope GRE tunnel is created and the entry is present in “sudo ovs-vsctl show” output. I could not see any real issue in your setup from the karaf logs.

Subject: [ovsdb-dev] Not successful in enabling L3 on ODL (Stable Kilo with ODL Lithium SR1 ) Hi I have two machines where in I simulated Multi node setup (2 compute nodes + 1 openstack controller + 1 Opendaylight) Integrated stable kilo devstack and latest release of ODL Lithium SR1 to use ODL as neutron backend and L3 forwarder. 1. Able to create networks (net1 and net2) 2. Able to launch VM's on the compute Nodes (VM1 in CN1 attached to net1 && VM2 in CN2 attached to net2) 3. Not able to ping between VM's, VM1 and VM2 - GRE is the network type
- Enabled L3 forwarding in ODL - etc/custom.properties
- Some more attributes are added in Openstack controller to inform it that we are using L3 from ODL
local.conf files can be downloaded from here compute Node local.conf : http://fpaste.org/263578/44136961/ password 12345 Controller Node local.conf : http://fpaste.org/263580/44136973/ password 12345 I am following the links : http://www.flaviof.com/blog/work/how-to-odl-with-openstack-part2.html http://www.flaviof.com/blog/work/how-to-odl-with-openstack-part1.html As told in the link, when the gre tunnel is created, flows are populated in table 0 and table 110 across all the nodes and when the router is created and network interfaces are attached to it from Horizon UI table 60 and 70 are not populated with L3 entries.

Hi Ravi
Thanks for sharing the configuration files, vll try and let you know
Can you please tell me whether we need to enable Kernel IP Forwarding for L3 to work in ODL.
FYI
I don't have multiple NIC cards and running 1 compute node in VM1 and openstack controller in VM2 of my laptop and another compute and ODL in two different VM's on the other PC.
net.ipv4.ip_forward=1
Thanks
Vikram

Hi,
I could see a Null pointer exception while programming tunnel rules and it is related to L2. In your case the missing flows are related to DVR
and L3_forwarding.
Please restart the setup (run ./unstack.sh and ./clean.sh) and bring-up from scratch. I have attached my sample conf files, which
I have used for testing Vxlan (Cross verify them with yours). I could see many PORT DELETE southbound and OVSDB Disconnect messages. Did you delete any network/port/ovsdbconnection? I hope GRE tunnel is created and the entry is present in “sudo ovs-vsctl
show” output.
I could not see any real issue in your setup from the karaf logs.

Subject: [ovsdb-dev] Not successful in enabling L3 on ODL (Stable Kilo with ODL Lithium SR1 )
Hi
I have two machines where in I simulated Multi node setup (2 compute nodes + 1 openstack controller + 1 Opendaylight)
Integrated stable kilo devstack and latest release of ODL Lithium SR1 to use ODL as neutron backend and L3 forwarder.
1. Able to create networks (net1 and net2)
2. Able to launch VM's on the compute Nodes (VM1 in CN1 attached to net1 && VM2 in CN2 attached to net2)
3. Not able to ping between VM's, VM1 and VM2
- GRE is the network type
- Enabled L3 forwarding in ODL - etc/custom.properties
- Some more attributes are added in Openstack controller to inform it that we are using L3 from ODL
local.conf files can be downloaded from here
compute Node local.conf :
http://fpaste.org/263578/44136961/
password 12345
Controller Node local.conf :
http://fpaste.org/263580/44136973/
password 12345
I am following the links :
http://www.flaviof.com/blog/work/how-to-odl-with-openstack-part2.html
http://www.flaviof.com/blog/work/how-to-odl-with-openstack-part1.html
As told in the link, when the gre tunnel is created, flows are populated in table 0 and table 110 across all the nodes and when the router is created and network interfaces are
attached to it from Horizon UI
table 60 and 70 are not populated with L3 entries.

Hi, When stack.sh is executed, I could see net.ipv4.ip_forward(2015-08-23 14:51:27.571 | net.ipv4.ip_forward = 1) being set in logs. Possible Issues in your setup: 1. In your setup all the nodes run as a VM across 2 physical machines. If the VM’s VNIC is not connected to the physical interface of the host machines, please connect it by following the links [1]/[2]. In the below picture, instead of external network you have another machine which will run 2 VM’s for compute and ODL (This is how your setup should look). 
2. In the control nodes local.conf HOST_IP and SERVICE_HOST are not configured and it should be control nodes IP. 3. In the compute nodes conf file SERVICE_HOST IP should be control nodes IP. 4. After doing the above setup try to create single VM per compute node across 2 machines for same tenant. Check if the ping between VM’s works or not. With this we can be sure that the ping works across the 2 machines. a. If it is not working use tcpdump to check where the packet is dropping. [1]http://www.innervoice.in/blogs/2013/12/02/linux-bridge-virtual-networking/ [2] https://blogs.oracle.com/ronen/entry/diving_into_openstack_network_architecture1 If everything works fine, then try ping between different tenants.

Subject: RE: [ovsdb-dev] Not successful in enabling L3 on ODL (Stable Kilo with ODL Lithium SR1 ) Hi Ravi Thanks for sharing the configuration files, vll try and let you know Can you please tell me whether we need to enable Kernel IP Forwarding for L3 to work in ODL. FYI I don't have multiple NIC cards and running 1 compute node in VM1 and openstack controller in VM2 of my laptop and another compute and ODL in two different VM's on the other PC. net.ipv4.ip_forward=1 Thanks Vikram
Hi, I could see a Null pointer exception while programming tunnel rules and it is related to L2. In your case the missing flows are related to DVR and L3_forwarding. Please restart the setup (run ./unstack.sh and ./clean.sh) and bring-up from scratch. I have attached my sample conf files, which I have used for testing Vxlan (Cross verify them with yours). I could see many PORT DELETE southbound and OVSDB Disconnect messages. Did you delete any network/port/ovsdbconnection? I hope GRE tunnel is created and the entry is present in “sudo ovs-vsctl show” output. I could not see any real issue in your setup from the karaf logs.

Able to create networks (net1 and net2) 2. Able to launch VM's on the compute Nodes (VM1 in CN1 attached to net1 && VM2 in CN2 attached to net2) 3. Not able to ping between VM's, VM1 and VM2 - GRE is the network type
- Enabled L3 forwarding in ODL - etc/custom.properties
- Some more attributes are added in Openstack controller to inform it that we are using L3 from ODL
