ip vrrp auth-type

Configures the type of authentication used on a Virtual Router Redundancy Protocol (VRRP) interface.
Syntax
ip vrrp auth-type { no-auth | simple-text-auth auth-text }
no ip vrrp auth-type { no-auth | simple-text-auth auth-text }
Command Default

No authentication type is configured on a VRRP interface.

Parameters
no-auth
Configures no authentication on the VRRP interface.
simple-text-auth auth-text
Configures a simple text string as a password used for authenticating packets on the interface. The maximum length of the text string is 64 characters.
Modes

Interface configuration mode

Usage Guidelines

If the no-auth option is configured, ensure that all interfaces on all devices that support the virtual router ID do not use authentication.

If the simple-text-auth option is configured, ensure that all interfaces on all devices that support the virtual router ID are configured to use simple password authentication with the same password.

The no form of this command removes the VRRP authentication from the interface.

Note: Authentication is not supported by VRRP-Ev3.
Examples

The following example configures no authentication on Ethernet interface 1/1/6.

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 no-auth

The following example configures simple password authentication on Ethernet interface 1/1/6.

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 simple-text-auth yourpwd
