To determine the Routing Engine mastership by checking the LEDs on either the craft
interface or the Routing Engine.
Physically check the LEDs on either the craft interface or the Routing Engine (depending
on which chassis the Routing Engine is installed). The Routing Engine that displays an
illuminated Master LED is the master Routing Engine.

If graceful switchover is configured, the command prompt will look as follows:
{backup}
user@host-re0>
{master}
user@host-re1>
With RE1 as master and RE0
If you are logged in to the master Routing Engine, log in to the backup Routing Engine by
using the following command:
user@host> request routing-engine login other-routing-engine
user@host> request routing-engine login other-routing-engine
Password: ########
{backup}
user@host-re0>
You are now logged in to the backup Routing Engine in slot

For routers with two Routing Engines, you can configure which Routing Engine is the
master and which is the backup. By default, the Routing Engine in slot 0 is the master
(RE0) and the one in slot 1 is the backup (RE1).
To modify the default configuration, include the
hierarchy level:
