Does OpenVswitch accept duplicate OpenFlow rules with different priorities? -


if set ovs run of controller , try add 2 flow rules identical except priority, allowed?

is there in openflow specification speaks this? (i did quick scan of spec , couldn't find anything).

the theoretical use case of might come if have controller multiple routing apps driving same switch. if not allowed of switch have put logic in filter out redundant rules.

the switch doesn't care, controller tells do. if add same rule (with same priority), old rule replaced new rule, there no duplicate. if add same rule different priority, have rule twice. note rule higher priority applied, rule lower priority not used until rule high priority removed.
