Configuring VRRP

Configuring VRRP
VRRP is an advanced routing feature that must be enabled with a license key. If you have purchased an
advanced license key, and have enabled routing on the device, you must activate your license as described in
the chapter entitled "Activating Licensed Features" in order to enable the VRRP command set. If you wish to
purchase an advanced routing license, contact Enterasys Networks Sales.

Purpose

To enable and configure the Virtual Router Redundancy Protocol (VRRP). This protocol eliminates
the single point of failure inherent in the static default routed environment by transferring the
responsibility from one router to another if the original router goes down. VRRP‐enabled routers
decide who will become master and who will become backup in the event the master fails.
