Configure the Upgraded Routing Engine:
You then switch over this backup Routing Engine to make it the master Routing Engine.
1.
Use the
request chassis routing-engine master (acquire | release | switch)
to switchover the RE1-CB1 to become master host subsystem. All FPCs reboot after
this step.
Replace the Routing Engine RE0 with the RE-PTX-X8-64G Routing Engine.
2.
Use the request chassis routing-engine master (acquire | release | switch)
3.
to make the Routing Engine RE0 as the backup Routing Engine.
Configure the new backup Routing Engine RE0 by using the

Before you replace a Routing Engine, you must take the host subsystem offline. The host
subsystem is taken offline and brought online as a unit. Be aware of the effect of taking
a host subsystem offline on traffic, forwarding, and routing. See
