This argument is case sensitive.• When md5 authentication applies, it must be a plaintext string of 1 to 8 characters or a ciphertextstring of 24 characters if the cipher keyword is not specified, or a ciphertext string of 1 to 41characters if the cipher keyword is specified.• When simple authentication applies, it must be a plaintext string of 1 to 8 characters if the cipherkeyword is not specified, or a ciphertext string of 1 to 41 characters if the cipher keyword isspecified.DescriptionUse vrrp vrid authentication-mode to configure authentication mode and authentication key for a VRRPgroup to send and receive VRRP packets.Use undo vrrp vrid authentication-mode to restore the default.By default, authentication is disabled.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 addressof the VRRP group.You might configure different authentication modes and authentication keys for the VRRP groups on aninterface. However, the members of the same VRRP group must use the same authentication mode andauthentication key.Related commands: display vrrp.Examples# Set the authentication mode to simple and authentication key to Sysname for VRRP group 1 onVLAN-interface 2 to send and receive VRRP packets. system-view[Sysname] interface vlan-interface 2[Sysname-Vlan-interface2] vrrp vrid 1 virtual-ip 10.1.1.1[Sysname-Vlan-interface2] vrrp vrid 1 authentication-mode simple Sysnamevrrp vrid preempt-modeSyntaxvrrp vrid virtual-router-id preempt-mode [ timer delay delay-value ]undo vrrp vrid virtual-router-id preempt-mode [ timer delay ]
