It's not 1 to 1, which this model seems to assume.
Is that true? I think the documentation implies that, but I'm not sure if the implementation does. In the Logical_Port table, there can be zero or one "phys_endpt". If someone doesn't populate "phys_endpt" (or sets "type" to "vlan" and "ingress_encap" to the vlan id), then it should have the behavior that you describe. I spoke with Darrell at some length today, and I think he'll be sending out a revised version. I think the final version is supposed to behave like this: If "phys_endpt" is empty or exists with only a vlan tag, then it will behave just like it does now: the bindings will happen on any hypervisor with the appropriate "external-ids:ovn-bridge-mappings" set. If "phys_endpt" specifies a particular chassis, then it would only be instantiated there. (I think this latter case could be useful when creating a software gateway.) I need to read the localnet implementation and Darrell's proposed changes more carefully, but does the previous paragraph sound reasonable? I'll dig into it more tomorrow, but please let me know if I'm way off course. --Justin _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
