key: Sets the authentication key. This argument is case sensitive.
• When md5 authentication applies, it must be a plaintext string of 1 to 8 characters or a ciphertext
string of 24 characters if the cipher keyword is not specified, or a ciphertext string of 1 to 41
characters if the cipher keyword is specified.
• When simple authentication applies, it must be a plaintext string of 1 to 8 characters if the cipher
keyword is not specified, or a ciphertext string of 1 to 41 characters if the cipher keyword is
specified.
Usage guidelines
For security purposes, all keys, including keys configured in plain text, are saved in cipher text.
Before executing the command, create a VRRP group on an interface and configure the virtual IP address
of the VRRP group.
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 0/1 to send and receive VRRP packets.
<Sysname> system-view
[Sysname] interface gigabitethernet0/1
[Sysname-GigabitEthernet0/1] vrrp vrid 1 virtual-ip 10.1.1.1
[Sysname-GigabitEthernet0/1] vrrp vrid 1 authentication-mode simple Sysname

vrrp vrid preempt-mode
Use vrrp vrid preempt-mode to enable preemption on the router and configure its preemption delay in
a specific VRRP group.
Use undo vrrp vrid preempt-mode to disable preemption on the router in a specific VRRP group. As a
result, the router operates in non-preemptive mode.
Use undo vrrp vrid preempt-mode timer delay to restore the default preemption delay.
Syntax
vrrp vrid virtual-router-id preempt-mode [ timer delay delay-value ]
undo vrrp vrid virtual-router-id preempt-mode [ timer delay ]
Default
The router operates in preemptive mode and the preemption delay is zero seconds.
