I have starting playing around with OVS and try to connect 2 host devices with different IP domains (ie. 10.10.11.2 / 10.10.10.2), to do this I create 2 different bridges and connect each port to its respective switch. I was expecting that the linux routing will be able to create a connection between this two bridges and be able to communicate between host1 and host2. Here is the example I am using: http://groups.geni.net/geni/wiki/HowTo/ConfigureOVSWithLayer3Routing. For some reason, I am unable to establish communication between the hosts. Maybe you have encounter some similar issue? If you have good examples of other projects using OVS, could it be possible to send it my way?

Thank you

Kommentar zu bosh-lite – Error 100: Permission denied @ dir_s_mkdir – /vagrant/tmp von Sravan Kumar https://www.evoila.de/de/blog/2015/04/27/howto-fix-bosh-lite-deployment-with-error-error-100-permission-denied-dir_s_mkdir-vagranttmp/#comment-16 Tue, 31 Oct 2017 10:54:53 +0000 https://www.evoila.de/?p=3643#comment-16 This worked with my vagrant vm. Somehow the /vagrant/ got created with root permissions.
After changing the permissions, issue got resolved.

Great Article , however I have one doubt if you can help me in it. I do understand the entire concept here but before this even starts when the VM1 will try to reach to the VM2 , it will check for the arp entry in its table as both are in the same subnet. Considering it as a fresh setup how does the VM1 arp request is forwarded to the VM2 across the L3 devices.

Regards
Hemant

1. How the source / Destination VM send its ethernet frame to the VTEP . Since Vm1 has the MAC address of Vm2 it will always try to send the same to VM2 directly, So how come the frame from VM1 will be send to VTEP.

Thanks again….

But when I restart/shut down my machine ,the modules of openvswitch already removed and also after doing modprobe openvswitch is not working properly.Database connection failed is the error. Due to this ,I have to install again n again openvswitch ,which is very hectic.Is there any solution for this ? Please give me guidelines.
