Thanks Scott and Roman. I’ll try that. Thanks, Monica

The default action in OF1.3+ is to drop such packets. FWIW To simplify debug of the flows I'd recommend to add a fall-through flow in table 0, with the lowest priority 0, to send not matching packets to controller. In the controller you might just print headers of the not-matched packets.

[SL] I am pretty sure there is a way, but I am not familiar with how to enable that functionality (I haven't personally seen the behavior you're describing). Setting the OVS fail_mode to "secure" might help, see "man 5 ovs-vswitchd.conf". > Thanks, > Monica > > > -----Original Message----- > From: Scott Lowe > [mailto:scott.l...@scottlowe.org<mailto:scott.l...@scottlowe.org>] > Sent: Friday, March 18, 2016 11:08 AM > To: Rajasekaran, Monica > <monica.rajaseka...@us.fujitsu.com<mailto:monica.rajaseka...@us.fujitsu.com>> > Cc: discuss@openvswitch.org<mailto:discuss@openvswitch.org> > Subject: Re: [ovs-discuss] Namespaces connectivity through OVS > > Please see my response below. > > >> On Mar 17, 2016, at 3:50 PM, Rajasekaran, Monica >> <monica.rajaseka...@us.fujitsu.com<mailto:monica.rajaseka...@us.fujitsu.com>> >> wrote: >> >> Hi, >> >> I have two name spaces (10.0.0.1 and 10.0.0.2) connected via OVS.
