- VTN uses the configuration parameters from vtn.ini file for the OpenStack integration.
- These values will be set for the OpenvSwitch, in all the participating OpenStack nodes.
- A configuration file vtn.ini'' needs to be created manually in the 'configuration directory.
- The contents of vtn.ini should be as follows:
bridgename=br-int
portname=eth1
protocols=OpenFlow13
failmode=secure
- The values of the configuration parameters must be changed based on the user environment.
- Especially, "portname" should be carefully configured, because if the value is wrong, OpenDaylight controller fails to forward packets.
- Other parameters works fine as is for general use cases.
bridgename
- The name of the bridge in Open vSwitch, that will be created by OpenDaylight Controller.
- It must be "br-int".
portname
- The name of the port that will be created in the vbridge in Open vSwitch.
- This must be the same name of the interface of OpenStack Nodes which is used for interconnecting OpenStack Nodes in data plane.(in our case:eth1)
- By default, if vtn.ini is not created, VTN uses ens33 as portname.
protocols
- OpenFlow protocol through which OpenFlow Switch and Controller communicate.
- The values can be OpenFlow13 or OpenFlow10.
failmode
- The value can be "standalone" or "secure".
- Please use "secure" for general use cases.
