Hi Edison,
AFAIK, on standard OpenFlow Spec, there is no available action to send-back
packets from group table
to flow table.
OpenFlow Spec 1.3.5 says:
===
5.6 Group Table
===
...(snip)..., a bucket with no output or group action effectively drops the
clone of
the packet associated with that bucket.
===
OTOH, with Open vSwitch, it might be able to use NXActionResubmitTable.
Could you try this action?
http://ryu.readthedocs.io/en/latest/nicira_ext_ref.html#ryu.ofproto.ofproto_v1_3_parser.NXActionResubmitTable
e.g.)
actions = [parser.NXActionResubmitTable(table_id=1)]
buckets = [parser.OFPBucket(actions=actions)]
Thanks,
Iwase

Hi Iwase.
Thanks for helping me out.
According to the figure below I understood that I can send the packet from one flow table to the
group table.That's easy.
My problem is when I have to send the packet from one group table to another flow table in the pipe
line.
Best regards, Edison.

Hi Edison,
Sorry, I misunderstood.

It's a single switch with more than one FlowTable.
Consider that I need to insert a group (with it's buckets) after
Table_id = 0 and Table_id = 1.
You want to insert the same group entry into table:1 and table:2, right?
To insert a flow into the specified table (which has table_id), please add
"table_id" argument
to FlowMod class.
e.g.)
# insert into Table_id = 0
mod = parser.OFPFlowMod(
datapath=datapath,
table_id=0, # Table ID which you want to insert your flow into
...
instructions=instructions) # instructions include your group
action
datapath.send_msg(mod)
# insert into Table_id = 1
mod = parser.OFPFlowMod(
datapath=datapath,
table_id=1, # Table ID which you want to insert your flow into
...
instructions=instructions) # Note: the same "instructions"
instance can be reused.
datapath.send_msg(mod)
Thanks,
Iwase
Sorry if my English isn't good enough to provide a crystal clear
question.
Bests.
Edison.

What does "between two flowtables" exactly mean?
You mean "how to insert the same group action into two OpenFlow
switches"?
Or, "how to insert the same group entry into two OpenFlow
switches"?
Thanks,
Iwase
