The LAN workstations are configured with the address of the virtual router as their default
gateway, just as they are with HSRP, but VRRP differs from HSRP in these important ways:
uu VRRP is an IEEE standard (RFC 2338) for router redundancy; HSRP is a Cisco
proprietary protocol.
uu The virtual router that represents a group of routers is known as a VRRP group.
uu The active router is referred to as the master virtual router.
uu The master virtual router may have the same IP address as the virtual router group.
uu Multiple routers can function as backup routers.
uu VRRP is supported on Ethernet, Fast Ethernet, and Gigabit Ethernet interfaces, as well as
on Multiprotocol Label Switching (MPLS) virtual private networks (VPNs) and VLANs.
