Abstract
Client address based forwarding of dynamic host configuration protocol response packets may be provided. First, a first relay agent on a first network device may receive a first discovery message associated with a first client device. The first discovery message may include a first discovery message identifier field comprising a first identifier corresponding to the first client device. The first client device may be associated with a subnet. Then the first relay agent may register, with a map server, the first identifier with an address of the first network device and add a gateway address corresponding to the first relay agent to the first discovery message. Next, the first relay agent may encapsulate the first discovery message and forward the encapsulated first discovery message over a network to a border device.
