Default level
2: System level
Parameters
virtual-router-id
: VRRP group number, which ranges from 1 to 255.
md5
: Specifies the MD5 authentication mode.
simple
: Specifies the simple authentication mode.
cipher
: Sets a ciphertext authentication key.
key
: Set 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.
Description
Use
vrrp vrid authentication-mode
to configure authentication mode and authentication key for a VRRP
group to send and receive VRRP packets.
Use
undo
vrrp vrid authentication-mode
to restore the default.
By default, authentication is disabled.
For secrecy, 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 can 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.
Related commands:
display vrrp
