Configures the authentication type for a specific VRRP (Virtual Router Redundancy Protocol) router.
| vlan_name |
Specifies the name of a VRRP VLAN (Virtual LAN). |
| vridval |
Specifies the VRID of a VRRP instance. To display the configured VRRP router instances, enter the show vrrp command. |
| password |
Specifies the user-defined password for authentication. |
Authentication is set to none.
Note
This command applies only to VRRP routers configured only for VRRPv2 (configure vrrp vlan vrid version command, v2 option), and is only supported for backward compatibility. If you try to enter this command in the combined VRRPv2 and VRRPv3 mode or VRRPv3 mode, an error message appears.
This command can add a modest amount of security to VRRP advertisements. All VRRP routers using the same VRID must use the same password when using this feature.
A simple password must be between 1 and 8 characters long.
The following command configures authentication for VRRP VLAN vrrp-1 with the password newvrrp:
configure vrrp vlan vrrp-1 vrid 1 authentication simple-password newvrrp
This command was first available in ExtremeXOS 10.1.
This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the VRRP feature, see the ExtremeXOS 22.2 Feature License Requirements document.
