    The following requirements apply to all switches and Virtual Chassis:

     

    1. All Virtual Chassis members and all Routing Engines must be running the same Junos® OS release.
    2. Graceful Routing Engine switchover (GRES) must be enabled.
    3. Nonstop active routing (NSR) must be enabled.

     

    For configuring, we may add below changes to the switch:-

     

    1. GRES

     

    [edit chassis redundancy]

    graceful-switchover;

     

    1. NSR

     

    [edit routing-options]

    nonstop-routing;

    Don't forget NSB:

     

    {master:1}[edit]
    root@EX4200# show ethernet-switching-options                    
    nonstop-bridging;

    {master:1}[edit]
    root@EX4200#

    If this worked for you please flag my post as an "Accepted Solution" so others can benefit. A kudo would be cool if you think I earned it.

    You must also have the virtual-chassis configured in preprovisoned mode.
