Parameter 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 text
with a length of 1 to 8 characters.
■ When md5 authentication applies, the authentication key is in MD5 ciphertext
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 ciphertext, its length must be 24 characters, such as
_(TT8F]Y5SQ=^Q‘MAF4<1!!.
Description Use the
vrrp vrid authentication-mode command to configure authentication
mode and authentication key for the VRRP standby groups 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:
■ Before executing the command, create a standby group on an interface and
configure the virtual IP address of the standby group.
■ You may configure different authentication types and authentication keys for
the standby groups on an interface. However, the members of the same
standby group must use the same authentication mode and authentication key.
Example # Set the authentication mode and authentication key for VRRP standby group 1
on interface Ethernet 1/0 to send and receive VRRP packets.
