Chapter 22 Configuring Redundancy
In this example, Router-16 is the nondesignated MSFC; high-availability redundancy and configuration
synchronization are enabled:
Console>(enable) session 16
Trying Router-16...
Connected to Router-16.
Escape character is '^]'.
Router-16> enable
Router-16# configure terminal
Config mode is disabled on non-designated Router, please configure from designated Router
High-Availability Redundancy Configuration Examples
This section discusses different scenarios for enabling high availability and configuration
synchronization:
•
•
•
•
•
Scenario 1: Enabling Configuration Synchronization on Both MSFCs
This scenario assumes both MSFCs are up.
When you enable configuration synchronization on both MSFCs, the IP addresses on all the interfaces
are checked first. If an IP address is specified for the designated MSFC but not specified for the
nondesignated MSFC, a message is displayed indicating the first interface for which the alternate IP
address was not specified.
After checking IP addresses, the HSRP addresses are checked; if an HSRP address is specified for the
designated MSFC but not specified for the nondesignated MSFC, a message is displayed indicating the
first interface for which the alternate HSRP (standby) address was not specified.
After checking the HSRP addresses, the IPX network address is checked.
The designated MSFC is configured first. This example shows a missing alternate configuration for the
VLAN 1 interface:
Router-16# configure terminal
Enter configuration commands, one per line.
Router-16(config)# redundancy
Router-16(config-r)# high-availability
Router-16(config-r-ha)# config-sync
Alternate IP address missing for Vlan1
The alternate configuration is missing. The auto-config sync can not be enabled
Note When specifying the alternate IP configuration, the configuration specified before the alt keyword
relates to the MSFC on the supervisor engine in slot 1 of the switch; the configuration specified after
the alt keyword relates to the MSFC on the supervisor engine in slot 2. See the
section on page 22-33
