Hi Arun/Vishal,
Thanks for looking into this issue.
When I was trying with IPv6 Source address CIDR value is /64 (Mask) flow is
not getting programmed on the OVS switch.
Working Scenario:
Tried with CIDR /10 and /128 and flows are getting programmed properly
as expected.
Concerned Scenario:
It should work for any valid IPv6 CIDR range(/1 to /128). Please confirm
whether this range is supported or it is invalid?.
Thanks and Regards,
Karthukeyan.
