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. It is the open standard implementation of HSRP.
10.4.1. VRRP and HSRP Comparison
The LAN workstations are then configured with the address of the virtual router as their default gateway. VRRP differs from HSRP in these ways:
VRRP is an IEEE standard (RFC 2338) for router redundancy; HSRP ...
