Analysis of Cisco 7600 vro usage

Key Content of Cisco 7600 vro

Show bootvar

The EHSA standby mode provides the following features:

Automatic startup, and bootvar synchronization between active and redundant super engines.

Detects and determines the hardware signal in the active and redundant status of the super engine.

Clock Synchronization from active to redundant superengine every 60 seconds.

A redundant super engine is started, but not all subsystems are up. If the active super engine fails, the redundant super engine becomes fully operable.

An operational super engine is represented by replacing a failed unit with a redundant super engine.

Configuration and real-world RPR +:

 
 

  
  
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 
 
 

Restart the default automatic synchronization:

 
 

  
  
Router(config)# redundancy  
  
  
 
  
  
Router(config-red)# main-cpu  
  
  
 
  
  
Router(config-r-mc)# auto-sync standard  
  
  
 
  
  
Router(config-r-mc)# auto-sync bootvar  
  
  
 
  
  
Router(config-r-mc)# end  
  
  
 
  
  
Router# copy running-config startup-config 
 
 

Disable automatic synchronization. Only Enable automatic synchronization of active super engine registers.

 
 

  
  
Router(config)# redundancy  
  
  
 
  
  
Router(config-red)# main-cpu  
  
  
 
  
  
Router(config-r-mc)# no auto-sync standard  
  
  
 
  
  
Router(config-r-mc)# auto-sync config-register  
  
  
 
  
  
Router(config-r-mc)# end  
  
  
 
  
  
Router# copy running-config startup-config 
 
 

Display redundancy status:

 
 

  
  
Router # show redundancy states
  
  
 
  
  
How does This example perform FSU:
  
  
 
  
  
Router # config terminal
  
  
 
  
  
Router (config) # config-register 0x2
  
  
 
  
  
Router (config) # boot system flash slot0: c6sup22-jsv-mz.121-11.E
  
  
 
  
  
Router # copy running-config start-config
  
  
 
  
  
Router # hw-module reset
  
  
 
  
  
Router # redundancy force-switchover
  
  
 
  
  
Router #

7600 you can use the interface range Command, (y! E! A! H !)
  
  
 
  
  
Router (config-if) # interface range fastethernet 5/1-5, gigabitethernet 1/1-2
  
  
 
  
  
Router (config-if) # no shutdown
