Hi

It works very similar than HSRP but it is a standard, please check the following link:

The group in VRRP works like in HSRP, the group defines which devices will work on the same HSRP IP scheme (broadcast domain)

Below you will find some diferences:

HSRP Versus VRRP Comparison Table

HSRP	VRRP
Propietary	Standards based
RFC 2281	RFC 3768
Separate IP Address needed for the Virtual	Can use the physical IP Address of the Virtual, if needed, saving IP space.
One Master, One Standby, all others are listening	One Master, all other routers are backup
More familiar to most network engineers	Less familiar - yet very similar
Can track an interface for failover	Can track an interface for failover (depending on operating system and version, it can also track the reachability of an IP address)
All HSRP routers use multicast hello packets to 224.0.0.2 (all routers) for version 1 or 224.0.0.102 for version 2.	All VRRP routers use IP protcol number 112 (vrrp) to communicate via multicast IP address 224.0.0.18
All virtual router must use MAC address 0000.0c07.acXX where XX is the group ID.	All virtual routers must use 00-00-5E-00-01-XX as its Media Access Control (MAC) address
