Item Description

Enable track to VRRP Configure whether to associate the internal server on an interface with a VRRP group,

and specify the VRRP group to be associated.
When two network devices deliver both stateful failover and dynamic NAT, follow these
guidelines:

Make sure the public address of an internal server on an interface is associated with

only one VRRP group. Otherwise, the system associates the public address with the
VRRP group having the highest group ID.

To ensure normal switchovers between the two devices, you need to add the devices

to the same VRRP group, and associate dynamic NAT with the VRRP group.
