Classification: CPC H | IPC H

Claim 9:
10. A system comprising:
a processor, a computer readable memory and a computer readable storage medium associated with a dynamic host configuration protocol (DHCP) server;
program instructions to receive a DHCP packet;
program instructions to determine that the DHCP packet comprises tenant-specific option information;
program instructions to 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);
program instructions to determine that the DHCP packet with the tenant-specific option information has at least one of a link selection sub-option and a subnet selection option;
program instructions to configure a first field of a tenant-specific DHCP option frame format in the tenant-specific option information to denote an overlay protocol type that is used for tenant isolation in overlay virtual networks;
program instructions to configure a second field of the tenant-specific DHCP option frame format in the tenant-specific option information to uniquely identify a tenant in the multiple tenant cloud data center; and
program instructions to 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,
wherein the second field is used by the DHCP server to locally scope an address range to an address space of the tenant, and
the program instructions are stored on the computer readable storage medium for execution by the processor via the computer readable memory.
