Abstract
An apparatus receives an upper layer packet that includes data from a source device, a virtual private network (VPN) identification, a destination address, and a destination option type. The apparatus authenticates the upper layer packet by comparing the VPN identification of the received upper layer packet to a customer VPN identification. The apparatus determines whether the apparatus recognizes the destination option type of the upper layer packet. The apparatus discards the upper layer packet on a condition that the apparatus does not recognize the destination option type. The apparatus decapsulates the upper layer packet into a lower layer packet and transmits the decapsulated packet to a destination on a condition that the apparatus recognizes the destination option type.
