1. A method comprising:

  • associating a first network loopback Internet protocol (IP) address with a first logical communication channel;

    associating a second network loopback IP address with a second logical communication channel;

    replicating a particular packet to obtain a first packet and a second packet;

    adding, by a device and to the first packet, a first identifier associated with the first logical communication channel,the first identifier including a virtual local area network (VLAN) tag associated with the first logical communication channel;

    adding, by the device and to the second packet, a second identifier associated with the second logical communication channel,the second logical communication channel being different from the first logical communication channel;

    providing, by the device, the first packet via the first logical communication channel based on the first identifier included in the first packet; and

    providing, by the device, the second packet via the second logical communication channel based on the second identifier included in the second packet,the first packet and the second packet being provided by the device without using or maintaining an Address Resolution Protocol (ARP) table.
