| − | Like HSRP, Virtual Router Redundancy Protocol (VRRP) allows a group of routers to form a single virtual router. In an HSRP or VRRP group, one router is elected to handle all requests sent to the virtual IP address. With HSRP, this is the ''active'' router. An HSRP group has one ''active'' router, at least one ''standby'' router, and perhaps many listening routers. A VRRP group has one ''master'' router and one or more ''backup'' routers. The LAN workstations are then configured with the address of the virtual router as their default gateway.

| − | VRRP differs from HSRP in the following ways:
| |
| − | *VRRP is an IEEE standard (RFC 2338) for router redundancy
| |
| − | ** HSRP is a Cisco-proprietary protocol.
| |
| − | *The virtual router represents a group of routers, known as a VRRP group or virtual router group.
| |
| − | *The active router is referred to as the master virtual router.
| |
| − | *The master virtual router may have the same IP address as the virtual router group.
| |
| − | *Multiple routers can function as backup routers.
| |
| − | *VRRP is supported on Ethernet, Fast Ethernet, and Gigabit Ethernet interfaces, and with Multiprotocol Label Switching (MPLS), virtual private networks (VPNs), and VLANs.
