Virtual Router Redundancy Protocol (VRRP)

The Virtual Router Redundancy protocol is designed to handle default router failures by providing a scheme

to dynamically elect a backup router. The driving force was to minimize "black hole" periods due to the failure

of the default gateway router during which all traffic directed towards it is lost until the failure is detected.

Though static configuration of default routes is popular, such an approach is susceptible to a single point of

failure when the default router fails. VRRP advocates the concept of a "virtual router" associated with one or

more IP Addresses that serve as default gateways. In the event that the VRRP Router controlling these IP

Addresses (formally known as the Master) fails, the group of IP Addresses and the default forwarding role is

taken over by a Backup VRRP Router.

Use the VRRP Configuration page to enable or disable the administrative status of a virtual router.

To display the page, click LAN > L3 Features > VRRP > VRRP Configuration in the navigation tree.

• If you change the administrative mode, click Submit to apply the changes to the system.

This sets the administrative status of VRRP in the router to active or inactive.

Select Enable or Disable from the dropdown menu. The default is Disable.
