Claim:
1. A method comprising: retrieving, by a network device, priority data from an Internet protocol (IP) header of a packet, wherein the priority data comprises differentiated services codepoint (DSCP) data comprising six bits having a first three bits and a second three bits; forming, by the network device, a first tag including a first set of data in a first priority field of the first tag, wherein forming the first tag comprises copying the first three bits of the DSCP data into the first priority field; forming, by the network device, a second tag including a second set of data in a second priority field of the second tag, wherein forming the second tag comprises copying the second three bits of the DSCP data into the second priority field, such that when concatenated, the first three bits and the second three bits form the six bits of the DSCP data; encapsulating, by the network device, the packet with the first tag and the second tag to form an encapsulated packet; and forwarding, by the network device, the encapsulated packet.
