devices can be aggregated, and thus the reliability of the IRF virtual device is increased through
link redundancy.
Powerful network expansion capability. By adding member devices, the number of IRF ports and
network bandwidth of an IRF virtual device can be easily expanded. Each member device has its
own CPU and they can process and forward protocol packets independently. Therefore, the
processing capability of the IRF virtual device also can be easily expanded.
