option 1 bridge all traffic from br-ex and br-eth1 to one physical interface eth1
eth0 -- Internal network br-eth1 -- Data network(physnet1 may be) br-ex -- External network in addition to the above add br-proxy ovs-vsctl add-br br-proxy ovs-vsctl add-port br-proxy eth1 ip link set eth1 up ip link set eth1 promisc on ip link add eth1-br-proxy type veth peer name proxy-br-eth1 #(see google for what is veth pair if you do not know already) ip link add ex-br-proxy type veth peer name proxy-br-ex ovs-vsctl add-port br-proxy proxy-br-eth1 ovs-vsctl add-port b-proxy proxy-br-ex ovs-vsctl add-port br-eth1 eth1-br-proxy ovs-vsctl add-port br-ex ex- br-proxy option 2 add eth0 to br-ex assign eth0's ip address to br-ex instead . This interface will act as your internal network interface as well as a interface for external network. eth1 you can use as usual and add them to br-eth1 Thank you, Ageeleshwar K ________________________________ From: dhanesh1212121212 [dhanesh1...@gmail.com] Sent: Monday, May 12, 2014 12:59 PM To: openstack@lists.openstack.org Subject: [Openstack] Network node (neutron) , I have only two interface in my machine.
