Hi,
Thanks guys.
I realized why it was not working. It was because when I was trying to
insert new flows, previously I deleted the flows like this:
$ ovs-ofctl del-flows tcp:10.10.10.12:6633
and this cause to also delete the flows in table id 0 which suppose to
forward it to table 100. This is I checked with:
show openflow instance aggregate flows
Just a bit different question, is actions Forward to Controller, supported
in HP ?
Thanks,
Chandra
