[j-nsp] EX4200 Virtual chassis

[Darius Seroka]

It should work (tm), but generally I believe it is best practice to create
a VC on two unused switches but in your case if you have one in production
you may not have options. You could confirm with JTAC to get the best
official answer.

As mentioned in several other threads you should also disable split
detection if the VC has only two chassis.

virtual-chassis {
    no-split-detection;
    member 0 {
        mastership-priority 255;
    }
    member 1 {
        mastership-priority 255;
    }
}

Aslo if you are making use of the out of band management juniper recommends
to make use of vme
