Failover
Vyatta ( Cluster/VRRP )
The protocol achieves this by creation of virtual routers, which are an abstract representation of multiple routers
(master, backup)
VRRP (Virtual Router Redundancy Protocol)
routers share a VIP (virtual IP) that is managed by the VRRP process on each router
The backup router is constantly checking to make sure the primary router is up, if not, it takes over as the master router.
