Hi Deepak,

Please suggest which other approach you think is better here for Origin 
attribute?

When the interface is set as DHCPEnabled=true ; similar to the Origin 
attribute , the IP address, SubnetMask and Gateway will be set by the 
host. So we would need to consider this usecase also as a candidate for 
the new approach.

Thanks & regards,
Sunitha
