Thanks! I will try out and see which is the best solution for me. will
update here if it works for me :)

You're doing something that no one really wants to do (as far as I
know). I see this as not a real problem, therefore it doesn't need a
real solution.
You can use veths, I think.

Yea I saw that but my question is ...should I be changing that? I am sort
of new to ovs. is there any other way to connect switches?
Since the same packet is being forwarded by all switches it reaches that
recursion limit. so apart from increasing this limit ..do we have another
solution?
Thanks
You can increase MAX_RESUBMIT_RECURSION in ofproto-dpif-xlate.c.

yes Ben, you maybe right. I saw it in log file when i enabled debugging .

Is there a way to work around this? how can i remove this limit to see if
it crashes or not. are there any other way

Hi,
The kernel version is 3.8.0-38 ( Linux ccpu1 3.8.0-38-generic
#56~precise1-Ubuntu)
I think you are right. it is the kernel datapath which is used by the
patch ports. I am not too familiar with working you explained about
the backlog queue.
i will have to explore the suggestions that you have m
Are you using datapath in kernel or in userspace?
What's the kernel version?
If it's kernel DP, then patch ports are internal ports which during TX
inserts the packet (skb) into the CPU backlog queue (enqueue_to_backlog())
for later processing. Later on, the backlog queue is processed
(process_
There's no drop. The packets should have wondered somewhere. Find it :D
You set this up by a py script or manually? If not entirely by a script
which you surely have check, than I'm skeptical of a mistake. But
anyway, another suggestion is: manually delete 66th and link 65 with 67.
See if it's

Open vSwitch does not have such a check.

TTL doesnt seems to be the problem. i have considered that. anyhow if
you check the traffic in the output that i posted the TTL is set as
255. Also i dont think TTL should matter if we are forwarding packets
at layer 2.
I am guessing there is a check somewhere in OVS code which limits it.
if anyo
Dear,
Time to live behavior? Just my sense. I'm not very into this to be sure.
You can see from wireshark if it's really because of TTL.
