virtual-router-id: VRRP group number, in the range 1 to 255. 

simple: Plain text authentication mode. 

md5: Authentication using the MD5 algorithm.  

key: Authentication key, which is case sensitive.  

z 

When simple authentication applies, the authentication key is in plain text with a length of 1 to 8 

characters.  

z 

When md5 authentication applies, the authentication key is in MD5 cipher text or in plain text and 

the length of the key depends on its input format. If the key is input in plain text, its length is 1 to 8 

characters, such as 1234567; if the key is input in cipher text, its length must be 24 characters, 

such as _(TT8F]Y\5SQ=^Q`MAF4<1!!. 

Use the vrrp vrid authentication-mode command to configure authentication mode and 

authentication key for a VRRP group to send and receive VRRP packets. 

Use the undo vrrp vrid authentication-mode command to restore the default. 

By default, authentication is disabled. 

Note that: 

z 

Before executing the command, create a VRRP group on an interface and configure the virtual IP 

address of the VRRP group. 

z 

You may configure different authentication types 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. 

# Set the authentication mode and authentication key for VRRP group 1 on interface VLAN-interface 2 

to send and receive VRRP packets.
