Multiple tunnel_ips

Santosh
 

Hi All, 
 I believe if hardware vtep  publishes multiple tunnel ip ,  odl is assume to pick the first ip which would be used as ip address in the vxlan tunnel creation.

Is this something which could configured ?

Is this understanding holds true for boron or I am missing something here.

Do let me know.

Thanks
Santosh

Hi Santosh,

 

Could you clarify the question? When you say vxlan tunnel creation, you mean from OVS/Compute to VTEP or VTEP to VTEP?

 

Regards,

Vishal.

Hi vishal, 

I am referring to both scenario. I.e. ovs/ compute to vtep and vtep to vtep.

basically  how tunnel endpoint ip would be selected in case of multiple tunnel ips is published to odl from vtep .


Thanks
Santosh.

Adding netvit-dev as this is more of a netvirt question, plugin has nothing to do with how we setup tunnels.

 

Added Suneelu for inputs. I think when we get a Physical_Switch with multiple tunnel_ips we do setup multiple tunnels in ITM for it and not just the first one. Actual tunnel used depends on physical locator used when configuring a remote mac entry. I’ll have to look at code but Suneelu might be able to answer off top of his head.

Hi Santosh,

   If multiple tunnel ips are configured , which one to pick and use is undefined.

   Currently we are choosing the first tunnel ip from the mdsal tree and ignoring the second tunnel ip.

Thanks,

Suneelu
