[j-nsp] MC-LAG reliability

[Raphael Mazelier]

Hey,

My experience with VirtualChassis with a lot of them (you know where) is 
globally positive. In fact I dot not remember when a VC completly fail. 
This is not a perfect techno but it do the job for very low cost of setup.

On EX series you have no choice, afaik MC-LAG is not supported (unless 
on highend series).

On QFX I would hesitate. My tests are OK.
Running independent switches is more reliable indeed, but even with 
automation tool the cost of setup/maintenance is bit higher. (and in my 
actual work I have just no time to spend with network config 
unfortunately).
