The hierarchical protocol relation between VRRP backup group, management group, and HRP is shown in Figure 1

Figure 1  Hierarchical protocol relation between VRRP backup group, management group and HRP

• When the status of the VRRP backup group changes, the VRRP management group decides whether to change its own status.
• When the state of the VRRP management group changes, the system will notify HRP and the primary or the secondary configuration devices to change their states. In this way, backup configuration commands and session state information between two firewalls can be updated in time.
