4. Enter the MD5 password configuration using the ip vrrp auth-type command with a text password. The password will be
encrypted when saved in the configuration file. When an MD5 authentication password is configured on an interface, a syslog
message is displayed.
device(config-if-e1000-1/1/6)# ip vrrp auth-type md5-auth gy42mb
5. Verify the password on the interface using the show ip vrrp command.
device(config-if-e1000-1/1/6-vrid-1)# show ip vrrp

In this example, the auth-type is MD5 authentication where the entered password is encrypted. A show run command with
appropriate parameters will actually display the encrypted password, and you can use the enable password-display command
to actually display the encrypted password. The output verifies the type of authentication.
The following example enables MD5 authentication on Ethernet interface 1/1/6 and verifies the authentication type.
device# configure terminal
device(config)# router vrrp
device(config)# interface ethernet 1/1/6
device(config-if-e1000-1/1/6)# ip vrrp auth-type MD5 yourpwd
device(config-if-e1000-1/1/6-vrid-1)# show ip vrrp

Abdicating VRRP master device status
Changing the priority of a VRRP master device allows a temporary abdication of the master device status to allow a backup device with a
higher priority to assume the master device role.
A VRRP session must be configured and running.
When you change the priority of a VRRP owner, the change takes effect only for the current power cycle. The change is not saved to the
startup configuration file when you save the configuration, and it is not retained across a reload or reboot. Following a reload or reboot,
the VRRP owner again has priority 255.
