[sfc-dev] ODL Log Message while configuring the SFC

Hi

I am able to bring up Ubuntu15 and installed OVS as per the reference link [1] suggested by Brady. But, the newly installed OVS (with NSH support) is not behaving properly. The bridge (e.g ovs-vsctl add-br mybridge) creation is resulting in error.

Query-1:  Is the following OVS with NSH aware installation procedure proper

                  Step-1: Remove the existing OVS on Ubuntu15 Box
                  Step-2: Install the OVS as per the link [1]   
                  Step-3: Created a binge (e.g ovs-vsctl add-br mybridge).   The step is not success.  


Query-2 : Is there any "OVS binary distribution" with NSH support ?

bringup OVS as NSH aware

Hi Brady

Thanks for pointing out this link.   I am trying to bring up the right OS environment as per the  note in the link (  reference [1]  ) .   My Ubuntu is 16.04  with kernel version 4.8.0-54-generic on  x86_64 box.  I can create VM for this purpose.

Query - 1: Can I get  Ubuntu 15.10image ?
Query - 2: Is this possible in Ubuntu 14.04 / Ubuntu 16.04


Thanks in Advance


[1] . The version should built is 2.5.90. This version is not compatible with kernel versions newer than 4.3.x. It works on Ubuntu 15.10 for example. More information available on in this

Brady Allen Johnson ---06/12/2017 06:33:14 PM---Dhevendran, Looks like you're not using a version of OVS with NSH installed. As you mentioned there

Dhevendran,

Looks like you're not using a version of OVS with NSH installed. As you mentioned there are no flows with VXLAN-GPE (notice its gpe (generic protocol encapsulation), not gre) but more importantly, no flows with NSH.

You can use this link to install OVS with NSH:

https://wiki.opendaylight.org/view/Service_Function_Chaining:Main#Building_Open_vSwitch_with_VxLAN-GPE_and_NSH_support

Regards,

Brady

Hi Brady 

Thanks for your immediate response (along with the patch update).  With your patch, we are able to see the configuration of SFFs on OVS.   But, our dump-flows results as follows (not matching with your result). By looking at this, it is clear that the VXLAN-GRE tunnel flows are missing. 

Query-1 :  It would be great if you guide us to create the missing (or correct) topology for this SFC environment.

Dhevendran, 

I have several answers from your internal discussions with Manuel. 

First of all, while using option 7 of the vnfmgr python script, you can ignore the messages related to "[RestConf-SFselect-HttpPut.json] does not exist". SFC uses SF selection algorithms when multiple SFs of the same type exist when creating a chain, and this REST json file selects which algorithm to use. But, if you dont manually specify it via REST, internally the random algorithm will be chosen by default. 

Regarding your question about the SF "rest-uri", that's an optional configuration that can be removed. There is a legacy SFC script called sfc-agent that received ODL southbound REST SFC configuration. The sfc-agent is no longer used. 

I see from your SF JSON that there are some deprecated fields in the configuration with respect to the latest version of ODL, such as the "nsh-aware" which has been moved to the SF-type model. I'll submit a patch now to the OPNFV SFC repo to update the config to the latest version of ODL, namely Carbon. 

Also, if you clone the ODL SFC repo, there are postman SFC examples that are updated to the latest in <sfc-repo>/resources/configuration-examples. 

I hope I covered all of your issues for now, but please let me know if you need any more help. 

Regards, 

Brady
