This is also great for planned maintenance. ISSU has not really worked
out for any of the vendors and with two small devices you can upgrade
them independently.
Great for aggregation, enables you to dual-home access devices into two
separate PEs that will never be down at the same time be it failure or
planned maintenance (excluding the physical issues like power/cooling
but dual-homing to two separate sites is always problematic for eyeball
networks).
