NOTE
This task supports VRRPv2 and VRRP-Ev2 only. VRRPv3 and VRRP-Ev3 are not supported.
1. From privileged EXEC mode, enter global configuration mode by issuing the configure terminal command.
device# configure terminal
2. Globally enable VRRP.
device(config)# router vrrp
3. Configure an Ethernet interface.
device(config)# interface ethernet 1/1/6
4. Enter the simple text password configuration using the
ip vrrp auth-type command with a text password.
device(config-if-e1000-1/1/6)# ip vrrp auth-type simple-text-auth yourpwd
5. Verify the password on the interface using the show ip vrrp command with either the VRID or Ethernet options.
device(config-if-e1000-1/1/6-vrid-1)# show ip vrrp

In this example, the authentication type is simple text authentication. A show running-config command with appropriate
parameters will actually display the password. The output verifies the type of authentication.
Configuring MD5 authentication on VRRP interfaces
Interfaces can be configured with an MD5 encrypted password for authentication, and VRRP can use the same authentication type
associated with the interfaces on which you define the virtual router ID (VRID).
If you configure your device interfaces to use an MD5 encrypted password to authenticate traffic, VRRP interfaces can be configured
with the same MD5 password, and VRRP packets that do not contain the password are dropped. If your interfaces do not use
authentication, neither does VRRP. Repeat this task on all interfaces on all devices that support the VRID.
1. From privileged EXEC mode, enter global configuration mode by issuing the configure terminal command.
device# configure terminal
2. Globally enable VRRP.
device(config)# router vrrp
3. Specify an interface associated with the VRRP VRID.
device(config)# interface ethernet 1/1/6
