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.

From the VRRP link, you can access the following pages:

To configure the global VRRP settings:

1. VRID is only configurable if you are creating new Virtual Router, in which case enter the

VRID in the range 1 to 255.

2. Use Interface to select the Unit/Slot/Port for the new Virtual Router from the pull-down

menu.
