Yes, geneve options are used. Specifically, there are three pieces of metadata sent: a logical datapath ID (the logical switch, or network), the source logical port, and the destination logical port. Geneve is only used between hypervisors. VxLAN is only used between hypervisors and a VTEP gateway. In that case, the additional metadata is not included. There's just a tunnel ID in that case, used to identify the source/destination logical switch on the VTEP gateway. > And if there are flow > commands available to add conditional flows at this time or if it is > possible to extend if need be. I'm not quite sure I understand this part. Could you expand on what you have in mind? -- Russell Bryant __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
