Configuring Supervisor Engine Redundancy
Configuration Mode Restrictions
The following configuration restrictions apply during the startup synchronization process:
• You cannot perform configuration changes during the startup (bulk) synchronization. If you attempt
to make configuration changes during this process, the following message is generated:
Config mode locked out till standby initializes
• If configuration changes occur at the same time as a supervisor engine switchover, these
configuration changes are lost.
Configuring Supervisor Engine Redundancy
These sections describe how to configure supervisor engine redundancy:
• Configuring RPR and RPR+, page 5-6
• Synchronizing the Supervisor Engine Configurations, page 5-7
• Displaying the Redundancy States, page 5-8
Configuring RPR and RPR+
To configure RPR or RPR+, perform this task:
This example shows how to configure the system for RPR+ and display the redundancy state:
Router> enable
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# redundancy
Router(config-red)# mode rpr-plus
Router(config-red)# ^Z
Router# show redundancy states
my state = 13 -ACTIVE
peer state = 1 -DISABLED
Mode = Simplex
Unit = Primary
Unit ID = 1
Redundancy Mode (Operational) = Route Processor Redundancy Plus
Redundancy Mode (Configured) = Route Processor Redundancy Plus
Split Mode = Disabled
Manual Swact = Disabled Reason: Simplex mode
Communications = Down Reason: Simplex mode
Command Purpose
Step 1
Router(config)# redundancy
Enters redundancy configuration mode.
Step 2
Router(config-red)# mode {rpr | rpr-plus}
Configures RPR or RPR+. When this command is
entered, the redundant supervisor engine is reloaded and
begins to work in RPR or RPR+ mode.
Step 3
Router# show running-config
Verifies that RPR or RPR+ is enabled.
Step 4
Router# show redundancy states
Displays the operating redundancy mode.
