VRRP configuration with a synchronization group

The examples in this section build on the the examples at Basic VRRP version 3 IPv4 configuration and Basic VRRP version 3 IPv6 configuration.

Here we add an interface to each system, specify a VRRP group and virtual IP address for these interfaces, and then include all interfaces in a synchronization group. Thus, if one of the interfaces on the master system fails, then all interfaces on the master system pass control to interfaces on the backup system.

Note: If an interface that belongs to a VRRP synchronization group is disabled then router failover services that are available through the VRRP feature are terminated for the given group. For a way to work around this, see VRRP Synchronization Group.
Note: To avoid state-failover oscillation between peers, we recommend that you do not enable preemption for synchronization groups.

The samples in this section create the configuration shown at VRRP with a synchronization group.
