[R3.0-25]:UI- disabling gateway for IPv6 subnet, sets the gateway as 0.0.0.0

[alok kumar]

While VN creation through contrail UI if we add ipv6 subnet with gateway disabled, gateway IP is set in IPv4 format however it should be in IPv6 format.

please check the snapshot attached.

Not sure if its a bug, Hari can comment. AFAIK 0.0.0.0 is used like a bool, it has nothing to do with ipv4 or ipv6

[Hari Prasad Killi (haripk)]

This should not cause any problem, as agent will see this as unspecified address and act accordingly. It is cosmetic - UI can decide on using :: or 0.0.0.0.

It's more of a consistency issue, similar bug was there in neutron/api which is fixed now.
