set protocols vrrp interface vrid authentication type

The set protocols vrrp interface vrid authentication type command configures an authentication mode for a VRRP group.

NOTE:

VRRP authentication is only supported by VRRPv2, which is not supported by VRRPv3.

Command Syntax

set protocols vrrp interface <interface-name> vrid <virtual-router-id> authentication type <none | md5 | simple>

Parameter

Parameter	Description
interface <interface-name>	Specifies the Layer 3 interface name of VRRP device. The value could be the VLAN interface name, the routed interface or the sub-interface name. The value is a string.
vrid <virtual-router-id>	Specifies the VRID of a VRRP group. The value is an integer that ranges from 1 to 254.
authentication type <none \| md5 \| simple>	Specifies the authentication mode. The value could be none, md5 or simple. none: Indicates no authentication. md5: Indicates MD5 authentication. simple: Indicates simple authentication. By default, there’s no authentication.

Usage Guidelines

NOTE:

Devices in a VRRP group must be configured with the same authentication mode and authentication key; otherwise, the VRRP group cannot negotiate the Master and Backup states.
If the VRRP authentication fails, the system prints the warning level log.

Example

Enable MD5 authentication mode for a VRRP group.
