Description

Syntax Description

vlan_name

Specifies the name of a VRRP VLAN (Virtual LAN).

Specifies the VRID of a VRRP instance. To display the configured VRRP router instances, enter the show vrrp command.

Usage Guidelines

Note

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.

Example

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

History

This command was first available in ExtremeXOS 10.1.
