VRRP has a long story of being encumbered by Cisco patents. It is better to use OpenBSD developed patent-free CARP protocol (Common Address Redundancy Protocol) as a replacement soluton. It is a lightweight, fast, reliable and security aware IP failover protocol. There is a userland implementation of CARP also for non-*BSD systems - visit

    I was an avid user of Keepalived in a production environment until we started having problems with it's stability.

    Mostly the problem was we would be on one stable release then the author would come out with a patch that would fix a problem but also introduce more functionality (including bugs).

    It burned us one to many times so management replaced it with a commercial solution.
