Looks like IPAM returns for IPv4 the next smallest unused address in the range of subnet address +1 (e.g. x.x.x.1) to biggest subnet address-1 (e.g. x.x.x.254). But from my experience the first port usually gets x.x.x.2. Can you give me a hint why it does not get x.x.x.1? > For DHCP here - > https://github.com/openvswitch/ovs/blob/master/ovn/northd/ovn-northd.c#L2662 > > Thanks > Numan > > Thanks and regards > > Dominik > > _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
