I don't know yet, figuring out a design would be the job of whoever takes that on.

This item comes from the analogy to physical networks: if I set up a router I can add as many routes to a link as I like. I don't have a particular use case for it, it's just for completeness in that analogy. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
