VRRP Configuration

AOS-W 2.2 supports redundant switch configurations using Virtual Router

Redundancy Protocol (VRRP) as the backup mechanism. Please see the

Redundancy Design Guide for more information on creating redundant

configurations.

OTE—Alcatel recommends that the redundant master switches be of the same

type (for example, OmniAccess 6000 to OmniAccess 6000) and configured

with the same version of AOS-W. The same applies to redundant local

switches (same class of switch running same version of AOS-W.

To enable VRRP, navigate to

Configuration > Switch > VRRP. The Virtual Router

Table will display all redundant networks in which the switch currently

participates.

FIGURE 9-16 Configuring VRRP

To add a new VRRP instance, click Add. Parameters available are the following:

Virtual Router ID – A unique identifier of the VRRP instance, also known as

VRID. This number should match the VRID on the other member of the

redundant pair, and must be between 1 and 255.

Advertisement Interval – This specifies how frequently VRRP announcements

are sent out. The default value is 1 second, or 1000 milliseconds. This value

must be the same on both members of the redundant pair.

Authentication Password – This password must be the same on both

members of the redundant pair. The password is sent in plain-text on the wire

and therefore should not be treated as a security mechanism. Rather, its

purpose is to guard against misconfiguration in the event that other VRRP

devices exist on the same network.
