<div>I have two VMs in
my setup each with
two interfaces.
Trying to setup the
VXLAN tunnels across
these interfaces
which are in
different subnets. A
docker container is
attached to ovs
bridge using
ovs-docker utility
on each VM and doing
a ping from one
container to
another.</div>

Hi Siva,<br>
<br>
I have a question. Are you able to ping between the two
interfaces on VM1 with this command?:<br>
<br>
# ping 20.20.0.183 -I eth1<br>
<br>
thanks,<br>
<br>

Well that's probably where my setup isn't configured right. What is
the output of 'ip route' on that system?<br>

<div>Hi,</div>
<div><br>
</div>
<div>I am trying to use local_ip
option for a VXLAN tunnel using ovs
but it does not seem to work. The
same works when I use GRE tunnel. I
also found a previous discussion
from another user who tried the
exact same approach. Here is the
link to the discussion</div>

<div>I am unable to find any working
resolution at the end of this
discussion. Could you please help?</div>

I looked into that but was never able to set
up a configuration like the one in that
discussion and could<br>
not repro the bug.<br>
<br>
Please provide some details on your usage,
configuration and steps to repro and I can
look into it.<br>
<br>
Thanks,<br>
