Chapter 22 Configuring Redundancy
Scenario 3: Designated MSFC Comes Up
In this scenario, Config Sync AdminStatus is enabled. The designated MSFC validates the alternate
configuration, allowing 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 22-39
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.
The following 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
A one-minute timer will start, allowing the nondesignated MSFC to stabilize. When the timer expires, a
snapshot of the current running configuration is sent to the nondesignated MSFC. The following
message is displayed before synchronizing the running configuration:
00:01:51: %RUNCFGSYNC-6-SYNCEVENT:
Syncing Running Configuration to the Non-Designated Router
Config Sync AdminStatus is Disabled
In this scenario, the nondesignated MSFC notifies the designated MSFC that it is up. Because the Config
Sync AdminStatus is disabled on the nondesignated MSFC, the designated MSFC displays the following
message indicating that high-availability redundancy needs to be enabled on the nondesignated MSFC:
Router-16#
Non-Designated Router came up.
High-Availability Redundancy Feature is not enabled on the Non-Designated Router
This example shows how to enable the high-redundancy availability feature on the nondesignated
MSFC:
Router-15# configure terminal
Enter configuration commands, one per line.
Router-15(config)# redundancy
Router-15(config-r)# high-availability
Router-15(config-r-ha)# config-sync
