user@router> request routing-engine
login ?
Possible completions: backup Log in to backup RE lcc Log in to LCC (0..3) master Log in to master RE other-routing-engine Log in to the other Routing Engine re0 Log in to RE0 re1 Log in to RE1 user@router> request routing-engine login lcc ? Possible completions: <lcc> Log in to LCC (0..3) user@router> request routing-engine login lcc 0 ? Possible completions: backup Log in to backup RE master Log in to master RE re0 Log in to RE0 re1 Log in to RE1
To manage the backup Routing Engines on all components (for example, to upgrade JUNOS software), log in to the TX Matrix platform backup Routing Engine and perform the necessary operations.
