request chassis routing-engine master (acquire | release | switch)
<force>
<no-confirm>
Command introduced before Junos OS Release 10.2 for J-EX Series switches.
For routers or switches with multiple Routing Engines, control which Routing Engine is
the master.
NOTE: Successive graceful Routing Engine switchover events must be a
minimum of 240 seconds (4 minutes) apart after both Routing Engines have
come up.
If the router or switch displays a warning message similar to "Standby Routing
Engine is not ready for graceful switchover. Packet Forwarding Engines that
are not ready for graceful switchover might be reset," do not attempt
switchover. If you choose to proceed with switchover, only the Packet
Forwarding Engines that were not ready for graceful switchover are reset.
None of the Flexible PIC concentrators (FPCs) should spontaneously restart.
We recommend that you wait until the warning no longer appears and then
proceed with the switchover.
acquire —Attempt to become the master Routing Engine.
release —Request that the other Routing Engine become the master.
—Toggle mastership between Routing Engines.

master Routing Engine.
Because both Routing Engines are always running, the transition from one to the other
as the master Routing Engine is immediate. However, the changeover interrupts
communication to the System and Switch Board (SSB). The SSB takes several seconds
to reinitialize the Flexible PIC Concentrators (FPCs) and restart the PICs. Interior gateway
protocol (IGP) and BGP convergence times depend on the specific network environment.
By default, the Routing Engine in slot 0 (RE0) is the master and the Routing Engine in
slot 1 (RE1) is the backup. To change the default master Routing Engine, include the
routing-engine statement at the [
configuration. For more information, see the Junos OS System Basics Configuration Guide
