Virtual Router Redundancy Protocol - Cisco Catalyst 4500 series Administration Manual

Chapter 1 Product Overview

Virtual Router Redundancy Protocol

Virtual Router Redundancy Protocol (VRRP) is a standard based first-hop redundancy protocol. With
VRRP, a group of routers function as one virtual router by sharing one virtual IP address and one virtual
MAC address. The master router performs packet forwarding, while the backup routers stay idle. VRRP
is typically used in the multi-vendor first-hop gateway redundancy deployment.
