Master, Backup and Line Card Switches

Master switch (RE0) One switch is elected Master

Master Route Engine (RE) runs JUNOS in amaster role

Runs all VC management daemons andcontrol protocols

Communicates with all VC member switchesfor interface OIR, forwarding hardwareprogramming, xmit/rcv updates

Line Card switches (LC) All other non-Master or Backup VC memberswitches

Runs JUNOS in a Line Card role

Responsible for programming local hardware

In the event of a Master or Backup failure, oneof the Line Card switches will be made the

new backup switch

Backup switch (RE1) One switch is elected Backup Backup RE runs JUNOS in a backup role

In sync with Master in terms of protocolstates and forwarding tables

Backup takes over control if Master fails

Virtual Chassis Management

Single management interface

Individual Ethernet management ports (me0) on Member switches aretied to a special management VLAN associated with a single L3 virtualmanagement interface (vme) by default

vme interface always follows the Master RE

best practice: Always configure the vme interface rather than the me0

interfaces

Single management IP address The virtual chassis is managed as a single network element; therefore it

will have only one management IP address that should be configured onvme interface

Single virtual console Connection to a console on any Member switch in a virtual chassis will

be redirected to the VC Master by virtual console software running on allMember switches
