Manually Switching Routing Engine Mastership
To manually switch the Routing Engine mastership, use one of the following CLI
commands.
•
From the backup Routing Engine, request the backup Routing Engine to acquire
mastership:
user@host> request chassis routing-engine master acquire
user@host> request chassis routing-engine master acquire
Traffic will be interrupted while the PFE is re-initialized
Request the other routing engine become master ? [yes,no] (no)
Resolving mastership...
Complete. The other routing engine becomes the master.
user@host> request chassis routing-engine master acquire
•
From the master Routing Engine, request the backup Routing Engine to acquire
mastership:
user@host> request chassis routing-engine master release
user@host> request chassis routing-engine master release
Traffic will be interrupted while the PFE is re-initialized
Request the other routing engine become master ? [yes,no] (no)
Resolving mastership...
Complete. The other routing engine becomes the master.
•
Switch mastership from either the backup or master Routing Engine:
user@host> request chassis routing-engine master switch
If graceful switchover is not configured, the command output looks as follows:
user@host> request chassis routing-engine master switch
warning: Traffic will be interrupted while the PFE is re-initialized
Toggle mastership between routing engines ? [yes,no] (no) yes
Resolving mastership...
Complete. The local routing engine becomes the master.
user@host> request chassis routing-engine master switch
If graceful switchover is configured the command output looks as follows:
Toggle mastership between routing engines ? [yes,no] (no) yes
Resolving mastership...
Complete. The other routing engine becomes the master.
When you enter the request chassis routing-engine master acquire command on the
backup Routing Engine, you see the following:
warning: Traffic will be interrupted while the PFE is re-initialized
Attempt to become the master routing engine ? [yes,no] (no).
