If you have written any interested OFv3 rspecs, feel free to add them at the bottom of this page and help others:-)

Rspec with one group

If you want to apply your packet filters to the same set of dpids, then you just need to create one group and use it in all your matches.

Rspec with multiple groups

If you need to apply different packet filters in different datapath sets, then you can create multiple groups and use them as needed in your matches.

Rspec with groups and datapaths

If for only one of your matches you need a different set of datapaths, you don't need to create a group you can just add the datapaths directly in your match.
