If you want to return routing control to the Routing Engine that was the master Routing
Engine at the beginning of the procedure (the default master Routing Engine), perform
the next task.
The switch can maintain normal operations with the Routing Engine in slot 1 acting as
the master Routing Engine after the software upgrade, so only perform this task if you
want to return routing control to the default master Routing Engine in slot 0.
Transfer routing control back to the default master Routing Engine:
1.
user@switch> request chassis routing-engine master switch
Verify that the default master Routing Engine (slot 0) is indeed the master Routing
2.
Engine:
user@switch> show chassis routing-engine
You will see:
