VRRP-Ev3 Overview

VRRP Extended version 3 (VRRP-Ev3) introduces IPv6 address support to the Extreme Networks proprietary VRRP Extended version 2 (VRRP-Ev2) protocol. VRRP-Ev3 is designed to avoid the limitations in the standards-based VRRPv3 protocol.

To create VRRP-Ev3, Extreme Networks has implemented the following differences from the RFC 5798 that describes VRRPv3 to provide extended functionality and ease of configuration:

VRRP-Ev3 does not include the concept of an owner device and a master VRRP-Ev3 device is determined by the priority configured on the device.
While the VRRP-Ev3 virtual router IP address must belong in the same subnet as a real IP address assigned to a physical interface of the device on which VRRP-Ev3 is configured, it must not be the same as any of the actual IP addresses on any interface.
Configuring VRRP-Ev3 uses the same task steps for all devices; no differences between master and backup device configuration. The device configured with the highest priority assumes the master role.

Note

VRRP-Ev3 is supported on the devices described in this guide. In a mixed-device environment, consult your documentation for the other devices to determine if VRRP-Ev3 is supported.

VRRP-Ev3 does not interoperate with with VRRPv2 or VRRPv3 sessions.
