[ovs-dev] OFPFMFC_OVERLAP Error

[varanasi sandhya]

Hi All

I am a master's student working on a project involving  RYU controller and
OpenVswitch on mininet.

OVS Version: 2.0.2

OFPFF_CHECK_OVERLAP flag Issue:

When OFPFF_CHECK_OVERLAP flag is set at RYU controller in ofctl_v1_3.py
code in the mod_flow_entry definition, OVS should ideally return
OFPFMFC_OVERLAP error on inserting a duplicate flow with same priority and
match. But instead the new flow entry just replaces the old flow.

I wanted to know how OFPFF_CHECK_OVERLAP condition should be used and if
there are any known issues using RYU controller and OpenVSwitch?

Any help would be appreciated.

Thanks and Regards
Sandhya Varanasi
