2229View Interface viewParameter virtual-router-id: VRRP standby group number, in the range 1 to 255.simple: Plain text authentication mode.md5: Authentication header (AH) authentication using the MD5 algorithm.key: Authentication key, case sensitive.■ When simple authentication applies, the authentication key is in plain textwith a length of 1 to 8 characters.■ When md5 authentication applies, the authentication key is in MD5 ciphertextor in plain text and the length of the key depends on its input format. If the keyis input in plain text, its length is 1 to 8 characters, such as 1234567; if the keyis input in ciphertext, its length must be 24 characters, such as_(TT8F]Y5SQ=^Q‘MAF4<1!!.Description Use the vrrp vrid authentication-mode command to configure authenticationmode and authentication key for the VRRP standby groups to send and receiveVRRP packets.Use the undo vrrp vrid authentication-mode command to restore thedefault.By default, authentication is disabled.Note that:■ Before executing the command, create a standby group on an interface andconfigure the virtual IP address of the standby group.■ You may configure different authentication types and authentication keys forthe standby groups on an interface. However, the members of the samestandby group must use the same authentication mode and authentication key.Example # Set the authentication mode and authentication key for VRRP standby group 1on interface Ethernet 1/0 to send and receive VRRP packets. system-view[Sysname] interface ethernet 1/0[Sysname-Ethernet1/0] vrrp vrid 1 virtual-ip 10.1.1.1vrrp methodSyntax vrrp method { real-mac | virtual-mac }undo vrrp methodView System view
