When deployed in a Virtual Chassis configuration, the EX2300
switches elect a primary and a backup switch based on a
set of preconfigured policies or criteria. The primary switch
automatically creates and updates the switching and optional
routing tables on all other Virtual Chassis switch members.
Switches can be added to or removed from the Virtual Chassis
