Release Information
Statement introduced in Junos OS Release 11.2.
Description
As part of the preprovisioned configuration for an MX Series Virtual Chassis, assign the role to be performed by each member router in the Virtual Chassis. The preprovisioned configuration permanently associates the member ID and role with the member router’s chassis serial number.
Options
routing-engine—Enable the member router to function as the master router or backup router of the Virtual Chassis configuration. The master router maintains the global configuration and state information for both members of the Virtual Chassis, and runs the chassis management processes. The backup router synchronizes with the master router and relays chassis control information, such as line-card presence and alarms, to the master router. If the master router is unavailable, the backup router takes mastership of the Virtual Chassis to preserve routing information and maintain network connectivity without disruption. You must assign the routing-engine role to both members of the Virtual Chassis. When the Virtual Chassis is formed, the software runs a mastership election algorithm to determine which of the two member routers functions as the master router and which functions as the backup router of the Virtual Chassis.
line-card—Explicitly configuring a member router with the line-card role is not supported in the current release. However, when split detection is enabled (the default behavior for a Virtual Chassis) and either the Virtual Chassis ports go down or the backup router fails, the master router takes a line-card role. The line-card role effectively removes the former master router from the Virtual Chassis configuration until connectivity is restored.
