Virtual Chassis

Juniper technology that interconnects multiple EX or QFX switches to be managed as a single logical device.

Definition

One member is primary Routing Engine, one is backup, and others are line cards. Members connect through dedicated or configured Virtual Chassis ports. Mastership priority controls election.

Example

set virtual-chassis member 0 mastership-priority 255

Exam tip

Configure equal top priority on the two intended Routing Engines to avoid unnecessary switchovers.
