Section14.1
Managing VRRP
The Virtual Router Redundancy Protocol (VRRP) is a gateway redundancy protocol. It provides a gateway failover
mechanism invisible to hosts and other devices that send traffic through the gateway.
VRRP eliminates a single point of failure associated with statically routed networks by providing automatic failover
using alternate routers. The RUGGEDCOM ROX II VRRP daemon (keepalived) is an RFC 5798 [http://tools.ietf.org/
html/rfc5798] version 2 and version 3 compliant implementation of VRRP.
NOTE
RFC 5798 defines the standard for VRRP version 3 on IPv4 and IPv6. Only IPv4 is supported in this
release of RUGGEDCOM ROX II.
