[SL] If you are adding multiple physical ports to the same OVS bridge, and those physical ports belong to the same broadcast domain, then I believe you're going to create a bridging loop. If you'd like to test to see if this is the problem, enable STP on the OVS bridge before adding eth3. > On Wed, Jul 20, 2016 at 11:17 PM, Scott Lowe <scott.l...@scottlowe.org> wrote: > Please see my response below. > > > > On Jul 20, 2016, at 5:04 PM, chetandeep singh <chetandeep.sin...@gmail.com> > > wrote: > > > > Hi Ben > > > > I have a primary eth port eth2 and secondary Ethernet port eth3 that does > > not have any ip assigned to the same.
