[ovs-discuss] Add overlap flows, which one would match?

Hi, all


What will happen when I add overlap flows with the same priority in OpenFlow 1.0.0?
OpenFlow Switch Specification Version 1.0.0  "4.6 Flow Table Modification Messages" says:


For valid (non-overlapping) ADD requests, or those with no overlap checking,
the switch must insert the flow entry at the LOWEST NUMBERED TABLE for which the
switch supports all wildcards set in the flow_match struct, and for which the
priority would be observed during the matching process.


Because the flow matchs from table 0, then table 1, ..., does it mean the latter
flow entry I added will match the flow?
