Claim 0:
1. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a dynamic host configuration protocol (DHCP) relay agent computing device to cause the DHCP relay agent computing device to:
configure a first field of a tenant-specific DHCP option frame format in a tenant-specific option information to denote an overlay protocol type that is used for tenant isolation in overlay virtual networks;
configure a second field of the tenant-specific DHCP option frame format in the tenant-specific option information to uniquely identify a tenant in a multiple tenant cloud data center;
configure a third field of the tenant-specific DHCP option frame format in the tenant-specific option information to denote a virtual network of the overlay virtual networks;
derive an encoding value of a transport agent in the tenant-specific option information in response to the DHCP relay agent computing device on a network virtualization edge (NVE),
wherein the second field is used by the DHCP server to locally scope an address range to an address space of the tenant.
