Chapter 22 Configuring Redundancy
Copy the Cisco IOS Release 12.1(8a)E2 or later image to the bootflash of the designated router and
Step 4
nondesignated router.
Step 5 Set the boot image and configuration register on the designated router and nondesignated router to boot
the new image on a reload:
For the designated router, enter boot system flash bootflash:image_name and ensure that this image is
the first in the boot list. Clear any existing "'boot system" commands that appear in the running
configuration (show running-config) using the no form of the boot system command.
For the nondesignated router, set the configuration register to auto boot by entering
config-register 0x102.
Enter the reload command to reload the designated router and nondesignated router.
Step 6
Note
Disable configuration synchronization (config-sync) on the designated router using the no form of the
Step 7
command. Enter the write memory command. This lets you have access to configuration mode on both
designated and nondesignated routers.
Enable SRM on the designated router first, and then enable SRM on the nondesignated router as follows:
Step 8
Router(config)#redundancy
Router(config-r)#high-availability
Router(config-r-ha)#single-router-mode
Enter the write memory command on the designated router to ensure that the nondesignated router's
Step 9
start-up configuration has SRM enabled.
Enter the show startup-config command on the nondesignated router to ensure that the nondesignated
Step 10
router has the following configuration statements:
redundancy
high-availability
single-router-mode
Enter the show redundancy command on the designated router and nondesignated router to ensure that
Step 11
both have the following configuration statement:
Single Router Mode RuntimeStatus: enabled
If not, repeat Steps 9 and 10 allowing sufficient time between steps.
Enter the reload command to reload the nondesignated router. When asked whether the configuration
Step 12
should be saved, enter no.
This display summarizes the above configuration commands used on the designated router and
nondesignated router to enable SRM redundancy:
