This example shows how the alt keyword is used when entering the ip address command:
Router-1(config-if)# ip address 1.2.3.4 255.255.255.0 alt ip address 1.2.3.5 255.255.255.0
Enabling or Disabling Configuration Synchronization
To enable high-availability redundancy, perform this task in privileged mode:
Task
Step 1 Enable redundancy.
Step 2 Enable high availability.
Step 3
Enable or disable configuration
synchronization.
This example shows how to enable high-availability redundancy and configuration synchronization
(Router-15 is the designated MSFC):
Console>(enable) session 15
Trying Router-15...
Connected to Router-15.
Escape character is '^]'.
Router-15> enable
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)# end
When you enable high-availability redundancy, the configuration mode is disabled on the
Note
nondesignated MSFC; only the EXEC mode is available.
