    your config on the 2 boxes should be the same in a virtual chassis (since it's the same management plane). So you'll need to have both members in the VC segment.

    Hi Sanjar,

    You don't need to add any config onto member 1 or any other member you want to add, although that won't hurt and will be just over writen.

    The reason they are not joining is because you need to add 

    "member 1 {
            role routing-engine;
            serial-number EZ2723AN0024;"

    to config on member 0
