Advanced Configuration and Management Guide

NOTE: For VRRP, change the router type only if you have moved the real IP address from one router to another or you accidentally configured the IP address Owner as a Backup.

For VRRPE, the router type is always Backup. You cannot change the type to Owner.

•Backup priority

•Suppression of RIP advertisements on Backup routes for the backed up interface

•Hello interval

•Dead interval

•Backup Hello messages and message timer (Backup advertisement)

•Track port

•Track priority

•Backup preempt mode

For VRRP, you can set some of these parameters using the VRRP configuration panel of the Web management interface, shown in “” on page 12-35.For information about the fields, see the parameter descriptions in the following sections. To access this panel, select VRRP from the System configuration sheet, then click Modify next to the VRRP entry you want to edit.

NOTE: You cannot set VRRPE parameters using the Web management interface.

See “VRRP and VRRPE Parameters” on page 12-9for a summary of the parameters and their defaults.

Authentication Type

If the interfaces on which you configure the VRID use authentication, the VRRP or VRRPE packets on those interfaces also must use the same authentication. HP’s implementation of VRRP and VRRPE supports the following authentication types:

•No authentication – The interfaces do not use authentication. This is the default for VRRP and VRRPE.

•Simple – The interfaces use a simple text-string as a password in packets sent on the interface. If the interfaces use simple password authentication, the VRID configured on the interfaces must use the same authentication type and the same password.

USING THE CLI

To configure the VRID interface on Router1 for simple-password authentication using the password “ourpword”, enter the following commands:

Configuring Router 1 Router1(config)# inter e 1/6

Router1(config-if-1/6)# ip vrrp auth-type simple-text-auth ourpword

Configuring Router 2 Router2(config)# inter e 1/5

Router2(config-if-1/5)# ip vrrp auth-type simple-text-auth ourpword

VRRP Syntax

Syntax: ip vrrp auth-type no-auth simple-text-auth <auth-data>

The auth-typeno-authparameter indicates that the VRID and the interface it is configured on do not use authentication.

The auth-typesimple-text-auth<auth-data> parameter indicates that the VRID and the interface it is configured on use a simple text password for authentication. The <auth-data> parameter is the password. If you use this parameter, make sure all interfaces on all the routers supporting this VRID are configured for simple password authentication and use the same password.
