Hello Vishal, Its a single flow (which is supported on OVS2.5) similar to IPv4 ping and impacts only IPv6. There will not be any change/impact to IPv4 pipeline. Currently we are not running IPv6 tempest scenario tests because of this.
As you know, we are adding new features in Netvirt and this is breaking IPv6 use-cases (fe., [1]). Sometimes we are not even aware that some existing IPv6 use-cases are broken. So, enabling tempest IPv6 scenario tests would help us to make sure that new changes are not creating issues to the existing IPv6 features. IMHO I don't feel that a spec is required for this use-case and would appreciate if we can get this in as soon as possible. [1] https://git.opendaylight.org/gerrit/#/c/57719/2 Thanks, --Sridhar.
