This is a good practice la..
in generic name call virtual interface, more specific name is loopback interface. It is a non-exist interface and always up.
Its function may vary, depends on how do you use it. In switch, it can use as
Vlan interface to route traffic. In router it can provide load balance/resilient link by specific loopback as next hop address instead of serial/ethernet interface. In protocol, it use as router ID..etc.

In your previous example, you also lose HSRP. Why don't get a load balancer such as foundry serveriron, it just cost around 6k for 8 ports in ebay.

冇睇其它load balancer呀.. 因為呢...一隻就話六千姐... 依家兩隻都係四千有找喎... hsrp仲未做... 搞清左個config先...唔係費是佢係咁switch黎switch 去..
