MSFC Redundancy
A 1-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. This 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 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
Router-15(config-r-ha)#
00:03:47: %SYS-5-CONFIG_I: Configured from console by console
00:03:47: %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 1-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. This message is
displayed before synchronizing the running configuration:
00:01:51: %RUNCFGSYNC-6-SYNCEVENT:
Syncing Running Configuration to the Non-Designated Router
These examples show that Config Sync AdminStatus and RuntimeStatus are enabled on the designated
and nondesignated MSFCs:
Router-15# show redundancy
Designated Router: 1 Non-designated Router:2
Redundancy Status: non-designated
Config Sync AdminStatus
Config Sync RuntimeStatus: enabled
Router-16# show redundancy
Designated Router: 1 Non-designated Router:2
Redundancy Status: designated
Config Sync AdminStatus
Config sync RuntimeStatus: enabled
