What is Virtual Router Redundancy Protocol (VRRP)?
Virtual Router Redundancy Protocol (VRRP) is a protocol that provides for redundancy in a network by switching to a backup router when the master router fails. The protocol gets its name because the master router and its backup routers share a virtual IP address. Using VRRP can increase the availability and reliability of your routing paths.
Under VRRP, the master and backup routers are all members of a redundancy group that forward the same packets as if there were only one router. But if the master router fails to do this, a new master is selected, and it then takes over the virtual MAC address of the previous master and forwards packets on behalf of it.
You can also use VRRP for load sharing.
VRRP is an open standard defined by RFC 5798. It is similar to Cisco's Hot Standby Router Protocol (HSRP), which is a proprietary protocol that Cisco has claimed has been infringed by VRRP.
