Chapter 23 Configuring Redundancy
Scenario 2: Disabling Configuration Synchronization on the Designated MSFC
In this scenario, the configuration synchronization is enabled. These examples show how to disable the
configuration synchronization:
Router-16# configure terminal
Enter configuration commands, one per line.
Router2(config)# redundancy
Router2(config-r)# high-availability
Router2(config-r-ha)# no config-sync
When the configuration synchronization is disabled, the following message is displayed on the
nondesignated MSFC:
00:13:00: %RUNCFGSYNC-6-SYNCEVENT:
The High-Availability Redundancy Feature is now disabled
The config mode is now accessible
Configuration mode is available on the CLI of the designated and nondesignated MSFC.
Scenario 3: Designated MSFC Comes Up
In this scenario, Config Sync AdminStatus is enabled. The designated MSFC validates the alternate
configuration, allowing the configuration synchronization to occur when the nondesignated MSFC
comes up.
Because the nondesignated MSFC is not up yet, Config Sync RuntimeStatus is disabled, and there is no
configuration synchronization. See the
page 23-41
This example shows that Router-16 is the designated MSFC, Config Sync AdminStatus is enabled, and
Config Sync RuntimeStatus is disabled:
Router-16# show redundancy
Designated Router: 1 Non-designated Router:0
Redundancy Status: designated
Config Sync AdminStatus
Config Sync RuntimeStatus: disabled
Scenario 4: Nondesignated MSFC Comes Up
Config Sync AdminStatus is Enabled
In this scenario, the nondesignated MSFC notifies the designated MSFC that it is up and Config Sync
AdminStatus is enabled. The designated MSFC requests the nondesignated MSFC to enable Config Sync
RuntimeStatus. The nondesignated MSFC enables Config Sync RuntimeStatus.
This message is displayed on the nondesignated MSFC:
00:00:07: %RUNCFGSYNC-6-SYNCEVENT:
The High-Availability Redundancy Feature is enabled
The config mode is no longer accessible
00:00:51: %RUNCFGSYNC-6-SYNCEVENT:
Non-Designated Router is now online
Running Configuration Synchronization will begin in 1 minute
