Hello Yngvi, You can make changes in /etc/network/interfaces as follows: 1. Define interface br-ex, give it static IP same as em3. 2. Add em3 to promiscuous mode.
Your interfaces file should look something like: *auto br-ex* *iface br-ex inet static* *address X.X.X.X* *netmask **X.X.X.X* *network **X.X.X.X* *dns-nameservers **X.X.X.X* *dns-search example.com <http://example.com>* *gateway **X.X.X.X* *auto em3* *iface em3 inet manual* *up ifconfig $IFACE 0.0.0.0 up* *up ip link set $IFACE promisc on* *down ip link set $IFACE promisc off* *down ifconfig $IFACE down* Hope this helps! -- Regards, Akshay On Wed, Mar 25, 2015 at 4:00 PM, Yngvi Páll Þorfinnsson <[email protected]> wrote: > Hi Andreas > Yes you're absolutely correct about this, when I use > ifconfig em3 0 > ifconfig br-ex 172.22.17.12/24 > I can ping the default gateway 172.22.7.1 > > But, how would you configure this permanently? i.e. how would you edit > the network configuration file: > /etc/network/interfaces > To make this a permanent configuration? > > Thanks a lot for your help ! > > Best regards > Yngvi > > -----Original Message----- > From: Andreas Scheuring [mailto:[email protected]] > Sent: 24. mars 2015 15:31 > To: Yngvi Páll Þorfinnsson > Cc: [email protected] > Subject: Re: [Openstack] openvswitch configuraion > > Hi Yngyi, > > this absolutely makes sense. > > As soon as you add a port to a bridge (doesn't matter if linux- or > ovs-bridge) it cannot be used as ip interface anymore.
