Configuring Redundancy
Synchronizing the Dynamic Information (Catalyst 8540 MSR)
Example
In the following example, both the startup and running configurations are synchronized:
Switch(config)# redundancy
Switch(config-r)# main-cpu
Switch(config-r-mc)# sync config both
Switch(config-r-mc)# end
Switch# copy system:running-config nvram:startup-config
Synchronizing the Dynamic Information (Catalyst 8540 MSR)
During normal operation, the dynamic state information about transit SVCs, transit or endpoint soft
PVCs, and point-to-multipoint soft PVCs, is synchronized by default between the primary and backup
route processors. Dynamic synchronization can be disabled if required.

Note
You must also enable synchronization of the running configuration to ensure synchronization of the
dynamic information.

Configuring Dynamic Information Synchronization (Catalyst 8540 MSR)
To synchronization the dynamic information about transit SVCs, plus, transit and endpoint soft PVCs
(both point-to-point and point-to-multipoint), during a route processor switchover, perform the
following steps on the primary route processor, beginning in global configuration mode:
