You might configure different authentication modes and authentication keys for the VRRP groups on an
interface. However, the members of the same VRRP group must use the same authentication mode and
authentication key.
Examples
# Set the authentication mode to simple and authentication key to Sysname for VRRP group 1 on
interface GigabitEthernet 1/0/1 to send and receive VRRP packets.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] vrrp vrid 1 virtual-ip 10.1.1.1
[Sysname-GigabitEthernet1/0/1] vrrp vrid 1 authentication-mode simple Sysname

Usage guidelines
The ARP entry backup function enables the master to back up the dynamic ARP entries of hosts to other
VRRP group members.
The ARP entry backup function is supported on Layer 3 Ethernet interfaces or subinterfaces.
Before you execute the command, create a VRRP group and configure a virtual IP address for it.
You can enable the ARP entry backup function when VRRP operates in either standard mode or load
balancing mode. Only the master can initiate ARP entry backup.
Enable ARP entry backup on all VRRP group members for the function to take effect correctly.
ARP entry backup affects VRRP performance. HP recommends not enabling the ARP entry backup
function for multiple VRRP groups.
