Chapter 5      Configuring RPR and RPR+ Supervisor Engine Redundancy
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+
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.
