In other hand we could set same lladdr on all ethernet > ifaces. The VIPA interface is an internal loopback, aka "virtual", as its name implies. Therefore it doesn't have an underlying link layer, so you can't do ARP on VIPA. The idea is to dynamically advertise this internal address to the outer world, so that in case one phy ifc would go down, the VIPA could still remain reachable via an alternative path/interface. To accomplish this goal you need to run a routing protocol - in my setup the plain old RIP 1 / routed combination worked just fine, although this was just an example...
