Optional settings

In addition to the basic configuration settings, you can change to the VRRP configuration in the following ways. All of these options apply to both IPv4 and IPv6 VRRP unless noted.

• Enable or disable individual virtual router configurations using the status option. Normally virtual router configurations are enabled but you can temporarily disable one if it is not required.
• Enable or disable preempt mode using the preempt option. In preempt mode, a higher priority backup router can preempt a lower priority primary router. This can happen if the primary router has failed, a backup router has become the primary router, and the failed primary router restarts. Since the restarted router has a higher priority, if preempt mode is enabled the restarted router replaces the current primary router becoming the new primary router. Preempt mode is enabled by default.
• You can add one or two destination addresses (vrdst) to a VRRP configuration. To be most effective, these destination addresses should be remote addresses.
