As the SDN is using Linux bridge only, and I want to stay with that, I see how to add an IP to the bridge itself, but not to To understand why virtualized environments require a new approach to switching, read the WHY-OVS document that is distributed with the source code. What I do are: (1) Binding UIO driver for NIC port (e. py --topo topo --mac --switch ovsk --controller remote So I wonder if there is any difference between these two commands? Allow changing the cloned MAC address for OVS bridges and interfaces. But I still prefer the standard linux network stack. VMs bridge to that OVS Bridge and most of them have a tag set in order to lock them to a single VLAN. For example, our example Create ovs vlan ports and assign ip addresses to them. The only mention of ports in the docs are "patch ports" as pairs of ports. 1. , on 172. Open vSwitch (OVS) is an open-source, multilayer virtual switch designed to enable efficient networking within virtualized environments. Depending on the tunneling protocol being used (this cookbook uses GRE), some configuration of the physical switches may be required (for example, it may be necessary to adjust the MTU). An option “lacp-fallback-ab” exists to provide such behavior on Open vSwitch. The main purpose of Open vSwitch is to provide a switching stack for hardware virtualization environments, while supporting multiple protocols and standards used in computer networks. The MAC address set on the bridge is propagated by ovs to the local interface (the one with the same name as the bridge), while all other internal interfaces use the address defined in According to documentation (man ovs-vswitchd. Bridge maintains a forwarding table, which stores {src_mac, in_port} pairs,and forwards packets (more accurately, frames) based on dst_mac. ) Having used OVS before, it is/was a charm to do similar, as you just add an OVSIntPort with the VLAN and IPs, and you are done. I am running Fedora 20 and using the native ifdown/ifup commands to configure the bridge (details of my network configuration files are at the bottom of this question).
